What is the phase angle relationship of current and the voltage dropped across a pure resistance?
The phase angle relationship of current and voltage dropped across a pure resistance.
Answer to Problem 1RQ
The phase angle between current and voltage in a pure resistance is zero degrees.
Explanation of Solution
In a pure resistance the current flowing in the resistance is in phase with the voltage drop across it. We say that phase difference between both parameters is zero degrees. The same can be seen in the phasor diagram shown above.
The ohms law for pure resistive circuit is written as,
It can be seen that there is no presence of any imaginary term in the equation above. Hence the phase angle is zero degrees.
