When different resistors are connected in parallel across an ideal battery,we can be certain that
A)there is the same current through each one.
B)the potential difference across each is the same.
C)the power dissipated in each is the same.
D)their equivalent resistance is greater than the resistance of any one of the individual resistances.
E)their equivalent resistance is equal to the average of the individual resistances.

Quizplus · Accepted Answer

In a parallel circuit, the potential difference (voltage) across each resistor is the same as the voltage of the battery. This is because each branch of the circuit has its own path for current to flow, and the voltage drop across each path is the same. Therefore, choice B is the correct answer.
