Calculating Applied Voltage in an Electric Circuit
What is the applied voltage in a circuit where a current of 9 A flows through an electric device with a resistance of 43 Ω?
A. 4.8 V
B. 387 A
C. 387 V
D. 4.8 A
Answer:
The correct option is (C) 387 V
Solution:
Given:
Electric current = 9 A
Resistance = 43 ohms
Using Ohm's Law:
V = I x R
Where:
V = applied voltage
I = electric current
R = resistance
Plugging in the values:
V = 9 A x 43 Ω = 387 V
Therefore, the applied voltage in the circuit will be 387 V.
