Current is the flow of electric charge in a circuit.
Current is measured in amperes (A).
It is the rate at which electric charge flows through a conductor.
Current can be either direct current (DC) or alternating current (AC).
In a DC circuit, the current flows in one direction only.
In an AC circuit, the current changes direction periodically.
Current is caused by the movement of electrons or other charged particles.
It is e...
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease the voltage in an electrical circuit.
