PHYS208 Fundamentals of Physics II

Hint for Ch. 33, 47E

a) - b) Set the arguments of the sine function for emf and current to pi/2 to find the maximum value.

c) Does the current lead or lag the emf? or is it in phase?

d) The ratio of the emf magnitude to the current magnitude is the impedance of the circuit. Use the appropriate formula for the contribution to the impedance for the circuit element determined in part c).
