Answer:
8V
Explanation:
Given parameters:
Current = 0.02A
Resistance = 400Ω
Unknown:
Voltage in the circuit = ?
Solution:
The voltage in a circuit is the driving force of the system.
According to ohms law;
V = IR
V is the voltage
I is the current
R is the resistance
So;
input the parameters and solve;
V = 0.02 x 400 = 8V
