Question
A rectangular coil of area 0.1 m2 and with 100 turns is rotated with a frequency, f= 50 Hz in a
uniform magnetic field of flux density, B
0.1T. The axis of rotation is perpendicular to the
%3D
magnetic field.
a) Derive an equation for the variation of voltage with time and calculate the root mean square
voltage.
b) If this voltage source is connected to a circuit containing two components in series, Z,=20+j150n
and Zz = 30 – j100 2, calculate the equivalent impedance.
c) Calculate the root mean square current and the average power in this circuit.
