Question

How much voltage is present in a circuit that carries 0.012 A with a resistance of 300 Ω?

Answer 1

3.6V

Step-by-step explanation:

Given parameters:

Current = 0.012A

Resistance = 300Ω

Unknown:

Voltage = ?

Solution:

According to ohm's law, voltage in a circuit is expressed mathematically as shown below:

Voltage = Current x Resistance

Insert the given parameters and solve;

Voltage = 0.012 x 300 = 3.6V
