A voltage source is connected to an electrical component X as shown in figure.
1. Identify the device X.
2. Which of the following equations can represent the current through the circuit?
- i = im sin(ωt + π/2)
- i = im sin(ωt – π/2)
- i = im sin ωt
- i = im sin(ωt + π/4)
3. Draw the phasor diagram for the circuit.
