Two identical incandescent light bulbs are connected as shown in figure. When the circuit is an AC voltage source of frequency f, which of the following observations will be correct.

Two identical incandescent light bulbs are connected as shown in figure. When the circuit is connected with an A.C. voltage source of frequency f, which of the following observation will be correct ?

Three identical bulbs P, Q and R are connected to a battery as shown in the figure. When the circuit is closed.

You are give many resistance, capacitors and inductors. These are connected to a variable DG voltage source (the first two circuits) or an AC voltage source of 50Hz frequency (the next three circuits) in different ways as shown in Column II. When a current I (steady state for DC or rms for AC) flows through the circuit, the corresponding voltage V_(1) and V_(2) (indicated in circuits) are related as shown in Column I. Match the column

In a circuit L, C and R are connected in series with an alternating voltage source of frequency f. when current in the circuit leads the voltage by 45circ the value of C.

If the four light bulbs in the following figure are identical which circuit gives out more light?
