Question

What is the effect of changing the wire in a circuit from a straight thick wire to
a longer (coiled) thick wire?
a) The bulbs become dimmer
b) The bulbs become brighter
c) The bulbs stay at the same level of brightness

Answer 1

Answer:

The bulbs become dimmer. What is the effect of changing the wire in a circuit from a straight thick wire to a longer (coiled) thick wire? The bulbs become brighter.

Explanation:

Answer 2

Answer:

The correct option is option D. The bulb stays at the same level of brightness.

If the two wires are switched or exchanged mutually, there will not be any change in the current are they will still remain in series and total resistance remains the same.

So the current will remain the same.

Hence the current through the bulb will remain unchanged. The brightness too will remain the same.

The length of the wire doesn't affect the brightness of the bulb. The brightness of the bulb depends on the current flowing through the wire.

The current will flow the same and the brightness will be unchanged if no resistor underwent a change.

The current is affected only by the resistance and here there is no resistance applied.

So, in this case, if the length of the wire is changed, still there won't be any change in the brightness of the bulb.
