Question 103

Two 5.0 Ω resistors and one 10.0 Ω resistor are connected in parallel with a cell of negligible internal resistance.

Which statement is correct?

A

The potential difference (p.d.) across each resistor is equal to the p.d. across the cell.

B

The current in the cell is equal to the current in each resistor.

C

The current through each of the three resistors is equal.

D

The potential difference across the 10.0 Ω10.0\ \Omega10.0 Ω resistor is twice the potential difference across the 5.0 Ω5.0\ \Omega5.0 Ω resistors.
