Question: Ohm's law for alternating current circuits is E = IZ, where E is the voltage in volts, I is the current in amperes, and Z

Ohm's law for alternating current circuits is E = IZ, where E is the voltage in volts, I is the current in amperes, and Z is the impedance in ohms. Each variable is a complex number.

(a) Write E in trigonometric form when I = 6 (cos 41° + i sin 41°) amperes and Z = 4 [cos (ˆ’11°) + i sin (ˆ’11°)] ohms.
(b) Write the voltage from part (a) in standard form.
(c) A voltmeter measures the magnitude of the voltage in a circuit. What would be the reading on a voltmeter for the circuit described in part (a)?
