Calculate the Applied Voltage in an Electric Device
Understanding Ohm's Law
Given Data
In this particular scenario, a current of 9 A flows through an electric device with a resistance of 43 Ω. The question is: What must be the applied voltage in this specific circuit?Potential Answers
The possible answers to this question are:- A. 4.8 V
- B. 387 V
- C. 4.8 A
- D. 387 A
Answer:
B. 387 V
Explanation:
Ohm's law states that the voltage is the product of the current and resistance.
V = IR
V = (9 A) (43 Ω)
V = 387 V
