Find the current though a 12-ohm resistive circuit when 24 volts is applied

I think for this question you can use Ohm's law to find this. To do so, look at explanation.

Explanation:

Ohm's Law and what is it?

V = I times R

I = current (rate of flow of electric charge)

R = resistance (opposition to flow of current)

V = voltage

Now ...

we have 12 ohms = r

v = 24 v

i = v/r

i = 24/12

i = 2 A (ampere)
