Question

19. Which of the following is the correct Ohm's law formula used to find resistance? A. R = I/E B. R = E/I C. R = PI D. R = EI

Answer 1

Ohm's Law is E = I*R; the version needed to find resistance is R = E / I (answer B)

Explanation:

Answer 2

For this case we want to apply Ohm's Law to find resistance.

By definition, Ohm's Law states that:

`E = I * R\\`

Where:

E: Voltage

I: Current

R: Resistance

Clearing the Resistance we have to:

`R = (E)/(I)\\`

Answer:

The Resistance is given by:
`R = (E)/(I)\\`

Option B
