Question

How many ohms of resistance must be present in a circuit that has 50 volts and a current of 2 amps.

Answer 1

Answer:

25 ohms

Explanation:

Hi there!

Ohm's law states that $V=IR$ where V is voltage, I is current and R is resistance.

Plug the given information into Ohm's law (V=50, I=2) and solve for R

$V=IR\\50=2R$

Divide both sides by 2 to isolate R

$\frac{50}{2}= \frac{2R}{2} \\25=R$

Therefore, there are 25 ohms of resistance present in this circuit.

I hope this helps!
