For the circuit shown in Figure Q2.1, use the Superposition Theorem to calculate:
i) The current flowing through the resistor R1
ii) The power consumed by R1
iii) The voltage dropped by R1
iv) Use Kirchhoff's Current Law (or otherwise) to calculate the current flowing through resistor R2
R1 = 3kΩ
R2 = 2kΩ
M1 = 20mA
Figure Q2.1
An alternating current waveform is given by I(t) = 15 sin (ωt + π/2). Find the following:
i) Peak current value
ii) RMS value of the current
iii) Peak-to-peak current value
iv) Frequency in Hertz
v) Initial phase angle
