All questions of Electricity for Year 9 Exam

Explanation:

Parallel Circuit with Identical Bulbs:
In a parallel circuit with identical bulbs, each bulb has its own separate branch connected directly to the voltage source. This means that the bulbs are not connected in series, but rather in parallel to each other.

Current Distribution:
In a parallel circuit, the current has multiple paths to flow through. Each branch of the circuit receives the full voltage from the source, but the current may split up and flow through each branch differently based on the resistance of each branch.

Current Sharing in Identical Bulbs:
When identical bulbs are connected in parallel, they have the same resistance. Since the resistance is the same for each bulb, the current flowing through each bulb will also be the same. This is because the current will divide equally among the branches in a parallel circuit.

Equal Current Sharing:
Therefore, in a parallel circuit with four identical bulbs, the current will be shared equally between them. Each bulb will receive the same amount of current, resulting in uniform brightness for all bulbs connected in the circuit.
In conclusion, option 'D' is the correct statement as in a parallel circuit with identical bulbs, the current is indeed shared equally between them.
