That's the idea. Don't forget the "j" in the inductor's impedance.Sylvia said:
Calculate the current and the voltage VPB. Put the results in polar form (magnitude and phase angle).Sylvia said:
? No calculus involved. Just circuit rules like Ohm's law.Sylvia said:
When you look at this closely, you can see that the question being asked is quite basic: what is the phase difference between current through an ideal inductor and the voltage across that ideal inductor.

The phase difference between voltage and current refers to the difference in timing between the two waveforms. It is measured in degrees and represents the delay between the peak of the voltage waveform and the peak of the current waveform.
The phase difference between voltage and current is important because it affects the power factor of an electrical system. A high power factor means that the voltage and current are in phase, resulting in efficient energy transfer. A low power factor, on the other hand, means that the voltage and current are out of phase, leading to energy loss and potential damage to electrical equipment.
The phase difference between voltage and current is measured using an oscilloscope or a power analyzer. These instruments can display the two waveforms and calculate the phase difference in degrees.
There are several factors that can cause phase difference between voltage and current. These include inductive and capacitive loads, which create a lag or lead between voltage and current respectively. Other factors include the length and type of electrical wiring, as well as the type of electrical equipment being used.
Phase difference between voltage and current can be corrected by using power factor correction techniques. This involves adding capacitors or inductors to the electrical system to counteract the effects of inductive or capacitive loads. Another way to correct phase difference is by using active power factor correction devices, which continuously monitor and adjust the power factor to maintain efficiency.
