Question
Chapter 36, Problem 1PLA
To determine
The phase relationship between the current in the resistor and the voltage across the resistor.
Expert Solution & Answer
Answer to Problem 1PLA
Option (c) the current is in phase with the voltage.
Explanation of Solution
For a resistance in series with an alternating current circuit, the direction of the flow of current is not changed due to the resistance. Therefore, the phase of the voltage and the current will be the same.
In other words, the current and voltage raise at the same time and falls at the same time. The minimum and maximum of the current and voltage will be the same.
Conclusion:
- (a) Current does not lead the voltage. Thus, option (a) is incorrect.
- (b) Voltage does not lead the current. Thus, option (b) is incorrect.
- (c) The current and the voltage are in phase with each other. Thus, option (c) is correct.
- (d) Option (c) is correct. Therefore, option (d) is incorrect.
