Question

What change in this circuit will make the bulb glow dimmer?

i) Use a bulb with a higher resistance
ii) Shorten the lengths of copper wire in the circuit
iii) Replace the two batteries with a single 4v battery.
iv) Use thicker wires to connect the battery to the bulb

Answer 1

Answer:

less resistance in the volt lower the the light will blow

Answer 2

Answer:

iv ) Use thicker wires to connect the battery to the bulb

Explanation:

because resistance = p l/A

so as area increases the resistance increases which will cause the bulb to glow dimmer
