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.

A linear electrical load draws I₁ A at a 0.72 lagging power factor. 11 = 153
When a capacitor is connected, the line current dropped to 122 A and the power factor
improved to 0.98 lagging. Supply frequency is 50 Hz.
a. Let the current drawn from the source before and after introduction of the capacitor be 1₁ and 12
respectively. Take the source voltage as the reference and express 11 and 12 as vector
quantities in polar form.
b. Obtain the capacitor current, Ic = I2 − I₁, graphically as well as using complex number
manipulation. Compare the results.
c. Express the waveforms of the source current before (i₁(t)) and after (i2(t)) introduction of the
capacitor in the form Im sin(2лft + 0). Hand sketch them on the same graph. Clearly label your
plots.
d. Analytically solve i₂ (t) - i₁ (t) using the theories of trigonometry to obtain the capacitor current
in the form, ic (t) = 1cm sin(2´ft + 0c). Compare the result with the result in Part b.
