Question

I think I am doing this correctly but can someone explain this to me in words spelled out on the simplest level so I can make sure I understand this. I've watched the Kahn academy video about leading and lagging and I think this is right but my professor hasn't explained it.

Determine the correct phase difference for the AC voltage/current shown -Voltage (V) -Current (A) o 120 10 240 300 360 420 480 40 600 660 720 Angle (degrees) Select one O a Current leads Voltage by 120 deg O b Current leads Voltage by 60 deg O c Voltage leads Current by 120 deg O d Current lags Voltage by 60 deg O e Voltage lags Current by 120 deg

Explanation / Answer

The fraction of a period difference between the peaks of voltage and current expressed in degrees is said to be the phase difference.

in these figures showing the angle in degrees in X-axis(horizontal axis). the difference of peak is expressed in the horizontal axis.

all answers are correct.

when the voltage is applied to an inductor, it resists the change in the current. then the current is lagging.

since the voltage on the capacitor directly proportional to charge then current will leads.
