The rotating loop in an AC generator is a square l on each side. It is rotated at frequency f in a uniform field of B. The generator is loaded with a resistor of resistance R. Give formulas in terms of l, B, f , and R for the following quantities:
a. the flux Φ (t) through the loop as a function of time
b. the emf Σ(t) induced in the lop
c. the current I(t) induced in the resistor
d. the power R(t) delivered to the resistor
e. the torque τ(t) that must be exerted to rotate the loop.
