Question

How can we change the magnitude of current in a circuit?

Answer 1

Answer:

If you have an inductance in the circuit the current will rise until the emf generated by the inductance equals the applied voltage. The current will then continue at a rate determined by the circuit resistance. The current may be varied by varying the input voltage, or by varying the resistance of the circuit.
