## determine the peak current drawn by the motor to determine the size of the circuit breaker needed to protect the circuit.

You are working in a factory and have been tasked with determining the electrical needs for a new motor that will be installed on an assembly line. The motor has been tested under load conditions and found to have a resistance of 35.0 Ω and an inductive reactance of 50.0 V. We can model the motor as a series RL circuit. The motor will have its own dedicated circuit with an rms voltage of 480 Ω. You need to determine the peak current drawn by the motor to determine the size of the circuit breaker needed to protect the circuit.

### determine the percentage of the total molar specific heat that is attributed to free electrons in gold.

The Dulong–Petit law states that the molar specific heat of solids is 3R at higher temperatures, where R is the gas constant. For metals, this law is obeyed at room….
