A circuit is a collection of electronic components that work together to make your device work. When you turn on your light switch, the circuit between the lightbulb and the wiring in your house creates electricity.

What is a circuit?
Jonny Nelson introduces an animated explanation of circuits. In series circuits, electrical components are connected one after another in a single loop. An electron will pass through every component on its way round the circuit.
What are the two types of circuits?
There are two types of circuit we can make, called series and parallel. The components in a circuit are joined by wires. If there are no branches then it's a series circuit. If there are branches it's a parallel circuit.
What happens when a circuit is in series?
In a series circuit, if a lamp breaks or a component is disconnected, the circuit is broken and all the components stop working. In a series circuit, if one lamp is removed or broken the other goes out Series circuits are useful if you want a warning that one of the components in the circuit has failed.
What are the rules of circuits?
Circuit rules An electron will not pass through every component on its way round the circuit. If one of the bulbs is broken then current will still be able to flow round the circuit through the other loop. If one bulb goes out, the other will stay on.
What is a circuit BBC?
In a television series, you get several episodes, one after the other. A series circuit is similar. You get several components one after the other.
What is a simple definition of a circuit?
In electronics, a circuit is a complete circular path that electricity flows through. A simple circuit consists of a current source, conductors and a load. The term circuit can be used in a general sense to refer to any fixed path that electricity, data or a signal can travel through.
What is a circuit GCSE?
Electrical circuits are connected in series or in parallel. Circuit components are shown as symbols. There are two types of current, alternating current (AC) and direct current (DC). Physics (Single Science)
What is a circuit ks3?
Circuit symbols Electrical components, like motors and lamps , can be connected together to form a circuit . A circuit diagram shows how the components are connected. Use straight lines to show the wires and circuit symbols to represent each component. Commonly used circuit diagram symbols.
What is the best definition of a circuit?
Definition of circuit an act or instance of going or moving around. a circular journey or one beginning and ending at the same place; a round.
What is a simple circuit ks2?
For a circuit to be complete, there must be wires connected to both the positive and negative ends of the power supply. A simple circuit can be made from a battery, a bulb and wires.

What is electricity BBC Bitesize ks2?
Electricity is created by generators which can be powered by gas, coal, oil, wind or solar. The electrical energy can be converted into other types of energy such as light, heat, movement or sound. Electricity is dangerous, so be careful when using electrical appliances.
What happens in a circuit?
When it is connected to a complete circuit, electrons move and energy is transferred from the battery to the components of the circuit. Most energy is transferred to the light globe (or other energy user) where it is transformed to heat and light or some other form of energy (such as sound in iPods).

What is a cell in a circuit?
A cell is a unit of device that converts chemical energy into electrical energy. 2. The function of a cell in a circuit is that the cell provides electrical energy to the circuit which produces current in it. 3. A cell supplies electric current.
What is the simplest type of circuit?
THE SIMPLEST CIRCUIT:OHM'S LAW.THE SIMPLEST CIRCUIT:The battery has a certain amount of push, called electromotive force or emf. ... The resistor has a determined amount of resistance measured in units called ohms. ... When current is flowing, we measure it in units called amperes, and indicate it with a letter I.I=E/R.More items...
Why is it called circuit?
This circular path, which is always required to get electricity to flow and do something useful, is called a circuit. A circuit is a path that starts and stops at the same place, which is exactly what we're doing.
What is a circuit class 6?
Answer: The electric circuit is an arrangement that provides a pathway for the flow of electric current. It is a device comprising of switches, bulbs, wires and an electric cell.
What are the two types of current?
Electrical current transfers energy around circuits. There are two types of current: direct and alternating.
What is the purpose of electrical current?
An electrical current heats the filament in a bulb so that it gives out light.
What is a diode?
Current will not flow in the other direction. Diodes are used to convert an alternating current into a direct current.
Who introduces an animated explanation of circuits?
Jonny Nelson introduces an animated explanation of circuits.
What are the two types of current?

What are the two types of circuits?
There are two types of circuit we can make, called series and parallel . The components in a circuit are joined by wires. If there are no branches then it's a series circuit. If there are branches it's a parallel circuit.
What is a series circuit?
A circuit with a battery and two lamps connected in series. If you put more lamps into a series circuit, the lamps will be dimmer than before. In a series circuit, if a lamp breaks or a component is disconnected, the circuit is broken and all the components stop working. Series circuits are useful if you want a warning that one ...
How do parallel circuits work?
In parallel circuits different components are connected on different branches of the wire. If you follow the circuit diagram from one side of the cell to the other, you can only pass through all the different components if you follow all the branches. A circuit with a battery and two lamps connected in parallel.
Why are parallel circuits useful?
And, unlike a series circuit, the lamps stay bright if you add more lamps in parallel. Parallel circuits are useful if you want components to continue to work, even if one component has failed. This is why our homes are wired up with parallel circuits. previous. 1.
Why is measurement and analysis important in circuits?
Measurement and analysis of current and voltage in simple circuits allows us to formulate rules and predict unknown values.
Why are series circuits useful?
Series circuits are useful if you want a warning that one of the components in the circuit has failed. They also use less wiring than parallel circuits.
How does the current in a series circuit work?
The current in a series circuit depends upon the number of cells. If you make the cells face in the same direction, the more cells you add , the greater the current. The current in this series circuit increases as more cells are added.
