Ohm's law for alternating current circuits is E = IZ, where E is the voltage in volts,
Question:
(a) Write E in trigonometric form when I = 6 (cos 41° + i sin 41°) amperes and Z = 4 [cos (11°) + i sin (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)?
