Question 22

Three resistors of resistance 2.0 Ω, 4.0 Ω, and 6.0 Ω are connected in series with an ideal cell.

Which statement is correct?

A

The current in each resistor is the same but the potential difference across each resistor is different.

B

The current in each resistor is different but the potential difference across each resistor is the same.

C

The potential difference across the 2.0 Ω2.0\ \Omega2.0 Ω resistor is three times the potential difference across the 6.0 Ω6.0\ \Omega6.0 Ω resistor.

D

The potential difference across each of the three resistors is equal to the electromotive force (e.m.f.) of the cell.
