In a simple PARALLEL RC circuit with two components of Resistor 150 Ohms and Capacitor 0.000000075F (75nF). AC supply 10V at 20,000Hz.
Impedance has a phase angle of -54.7 degrees if my calculations are correct.
What is it lagging -54.7 degrees behind? I suspect the answer is "Voltage supply" at 0 degrees but am unsure.
EDIT. Ill try to rephrase.
Can anybody complete this sentence:
"……" is lagging "……" by 54.7 degrees
This should enable me to understand what is at what angle
For reference my understanding of phase angle has now improved and I will attempt to explain the answer I was looking for.
In the above described circuit the phase angle is 54.7 degrees. This angle represets the phase difference in degrees between:
Resistance and Impedance.
Conductance and Admittance.
True power and Apparent power.
And most importantly, Current (which is in phase with Resistor voltage) and Supply voltage.
