Question

If the resistance of a circuit is 3 ohms, and the voltage produced by the cell in the circuit is 12 volts, what's the magnitude of the current?

Answer 1

Answer:

4 A

Explanation:

The magnitude of the current can be found by using the formula

$i = \frac{v}{r}$

v is the voltage

r is the resistance

From the question we have

$i = \frac{12}{3} = 4$

We have the final answer as

4 A

Hope this helps you
