Question

When comparing two circuits we note that the resistance is the same, but circuit one has more voltage. this means that

A) Both circuits will have the same current
B) Both circuits will have alternating currents
C) Circuit two will have more current
D) Circuit one will have more current

Answer 1

When comparing two circuits, we note that the resistance is the same, but circuit #1 has more voltage. This means that Circuit #1 will also have more current.

We only have to glance at Ohm's Law: I = E / R

Current = (voltage) / (resistance)

We can see plainly that if the voltage increases, then the current increases.
