Solution

The correct option is A is equal to the voltage of the battery
Let the resistance of each light bulb be $R_{1}$ and $R_{2}$ .
From figure, $V_{A B} = V_{C D} = V$
Also $V_{A B} = I_{1} R_{1}$ and $V_{C D} = I_{2} R_{2}$
Thus option A is correct.

Q. A 12-volt battery is connected to two light bulbs, as drawn in figure 1 light bulb 1 has resistance 3 ohms, while light bulb 2 has resistance 6 ohms. The battery has essentially no internal resistance, and all the wires are essentially resistanceless, too. When a light bulb is unscrewed, no current flows through that branch of the circuit. For instance, if light bulb 2 is unscrewed, current flows only around the lower loop of the circuit, which consist of the battery and light bulb 1. The more current flows through a light bulb, their equivalent resistance is

R_{e q} = R_{1} + R_{2}

. By contrast, when two reisistors are wired in parallel, their net resisance is given by

\frac{1}{R_{e q}} = \frac{1}{R_{1}} + \frac{1}{R_{2}}

Bulb 2 is now screwed in as a result, bulb 1 :

Q. Three similar light bulbs are connected to a constant voltage dc supply as shown in Fig. Each bulb operates at normal brightness and the ammeter (of negligible resistance) registers a steady current. The filament of one of the bulbs breaks. What happens to the ammeter reading and to the brightness of the remaining bulbs?
