Question 20 • Physical Science

Which equation is correct according to Ohm’s law?

Answer
A
cap r is equal to cap i cap v
B
cap i is equal to cap r over cap v
C
cap r is equal to cap i over cap v
D
cap v is equal to cap i cap r

Explanation

Ohm’s law states that voltage equals current multiplied by resistance: V = I × R. Therefore, the correct equation is “V is equal to I times R,” choice B. The other equations do not match Ohm’s law.
