Are AC and DC current same?
Electric current flows in two ways as an alternating current (AC) or direct current (DC). In alternating current, the current keeps switching directions periodically – forward and backward. While in the direct current it flows in a single direction steadily.
How do you convert AC to DC?
After Stepping down of voltage, AC is converted to DC using rectifiers. A full bridge rectifier can be used to convert AC to DC. In this device, 4 diodes are used which operates in forwarding bias and not in reverse bias.
Why is AC higher voltage than DC?
This is because generating and transporting AC across long distances is relatively easy. At high voltages (over 110kV), less energy is lost in electrical power transmission. Higher voltages mean lower currents, and lower currents mean less heat generated in the power line due to resistance.
What does 12V lighting mean?
