You are given many resistance, capacitors and inductors. These are connected to variable DC voltage source (the first two circuits) or an AC voltage source of 50 Hz frequency (the next three circuits) in different ways as shown in column II. When a current (steady state for DC or rms for AC) flows through the circuit , the corrresponding voltage V1 and V2 . (indicated in circuit) are related as shown in column I . match the two
