Question

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

Answer 1

25 ohms

Step-by-step 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

`(50)/(2)= (2R)/(2) \\25=R`

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

I hope this helps!
