When troubleshooting power and control circuits, approximate meter readings should be anticipated if the meter readings are going to be used to help determine circuit problems. Determine the expected DMM reading if the ciircuit is working properly. The expected reading of DMM 1 with the motor on is what VAC? And the expected reading of DMM 2 with the motor is on is what VAC? And The expected reading of DMM 3 with the motor on is What mA?

The input impedance of this antenna is 75 ohms, and it is attached ɔ a 50-ohm transmission line. The receiving antenna has an impedance mismatch at its terminals, - which leads to a VSWR of 2. The receiving antenna is about 95% efficient and has a field pattern near the beam maximum given by E, = (2âx + jây) F, (0, 0). The distance between the two antennas is 4,000 km, and the receiving antenna Directivity is 100.
