The change in current if one of the light bulbs in the given circuit is removed and the circuit is reconnected with a wire.
Explanation of Solution
Introduction:
The current in a circuit is inversely proportional to the resistance of the circuit.
Consider the circuit given in the question.
In the circuit, the three light bulbs are wired one after another in one branch; hence, the circuit is a series circuit.
As the bulbs of the series circuit are wired one after another, the amount of current is the same through every bulb.
Now, if one of the bulbs is removed and the circuit is reconnected with a wire, there will be only two bulbs in the circuit and the resistance due the removed bulb is also eliminated, so the total resistance decreases. Hence, the current increases.
Conclusion: There will be an increase in the current if one of the bulbs is removed and the circuit is reconnected with a wire, as the resistance of the circuit decreases on removal of a bulb.
