Question

A loop circuit has a resistance of R1 and a current of 2A. What is the voltage across the resistance?

a) R1/2
b) 2/R1
c) 2R1
d) 4/R1

Answer 1

The voltage across a resistance in a loop circuit can be calculated using Ohm's law. In this case, the voltage across the resistance is c) 2R1.

Step-by-step explanation:

The voltage across a resistance in a loop circuit can be calculated using Ohm's law, which states that V = IR, where V is the voltage, I is the current, and R is the resistance. In this case, the current is given as 2A and the resistance is R1. Therefore, the voltage across the resistance is 2A * R1 = 2R1.

So the correct answer is c) 2R1.
