Mei is an electrical engineer who has designed and built a robot

Mei is an electrical engineer who has designed and built a robot that can accurately launch tennis balls a great distance. She is testing her robot's design. 1. Mei is inspecting her robot's electronic circuits. Electrical engineers use complex numbers when calculating voltage and resistance. Part A The total voltage of a circuit is the sum of its sources. One of the robot's circuits has three source voltages (V), listed below. Find the total voltage of the circuit. Source 1: (9+41) V Source 2: (531) V Source 3: (2+61) V Part B Another circuit has two resistors in parallel with individual resistances R, and R. The total resistance R is given by the formula below. RI == RR R+R Find the total resistance. Write your answer in the form a + bi. ww R R R = 2+ iohms R = 1 + 2i ohms
