An AC generator consists of eight turns of wire, each having area A = 0.0890 m2, with a total resistance of 11.4 ?. The loop rotates in a magnetic field of 0.482 T at a constant frequency of 63.6 Hz.
(a) Find the maximum induced emf.
V
(b) What is the maximum induced current?
A
(c) Determine the induced emf and current as functions of time.
= ( V)sin(?t) I = ( A)sin(?t) ? =
(d) What maximum torque must be applied to keep the coil turning?
