The induced emf, ε , from a rotating coil in a magnetic field can be expressed as ε=ε0sinωt . If the coil provides a complete path for a current to flow, an induced current, I , is given by I=I0sinωt .
a. a What is the mean voltage being generated?
b. b What is the mean current flowing?
c. c Give an expression for the power being generated as a function of time.
d. d State the mean power being generated.
