Question

what must be the same for two resistors that are connected in parallel?

a. the rate at which energy is used by each

b. the resistance to the flow of charge of each

c. the rate at which charge moves through each

d. the potential difference across each

Explanation:

In a parallel circuit, the voltage (potential difference) across each component is the same. The rate at which energy is used (power, \(P=\frac{V^{2}}{R}\)) depends on resistance (\(R\)), so A is wrong. Resistance is a property of the resistor itself and not necessarily the same for two different resistors in parallel, so B is wrong. The rate at which charge moves (current, \(I = \frac{V}{R}\)) also depends on resistance, so C is wrong.

Answer:

D. The potential difference across each
