Question

3. Circuit A has twice the

resistance of circuit B. The
voltage is the same in each
circuit. Which circuit has the
higher current?

Answer 1

Circuit A

Step-by-step explanation:

Given:

R(A) = 2R(B)

V(A) = V(B)

.

Let's put these expressions in a formula for current:

.

`i = (v)/(r)`

`i(a) = (v)/(r)`

`i(b) = (v)/(2r)`

Since circuit B has a higher resistance, when dividing from a greater number, we get a smaller product

So, that means, circuit A will have a higher current
