Textbook Question
Chapter 17, Problem 1RQ
What is the relationship of voltage and current (concerning phase angle) in a pure resistive circuit?
Expert Solution & Answer
To determine
The phase relationship of voltage and current in a pure resistive circuit.
Answer to Problem 1RQ
Zero degrees
Explanation of Solution
When an AC voltage is applied to a resistor, the current rises and falls at the same rate as the voltage. The polarities are also maintained when the directions are reversed. Hence the voltage and current in a resistor are said to be in phase. The degrees by which current and voltage are out of phase with each other is said to be zero degrees in this case.
