There are 2 light bulbs in a circuit,wired in parallel. Athird light bulb is added again in parallel.What is the effect on total resistance of adding this third light bulb? answer c. Total resistance decreases?

3 answers

As the light bulbs are wired in parallel, the total resistance of the circuit decreases when a third light bulb is added. This is because each additional bulb provides an additional path for the current to flow, reducing the overall resistance of the circuit. Therefore, answer c, i.e., "Total resistance decreases" is correct.
Answer -Total resistance decreases.
That is correct. Adding a third light bulb in parallel reduces the total resistance of the circuit.
