A motor takes 38 amperes on a 220-volt circuit. Find the horsepower output (hp) of the motor shown with an efficiency of 90%. Ex
1 answer:
This question involves the concepts of power and current.
The power output of the motor is "10.08 hp".
<h3>Power Output</h3>The power output of the motor can be found using the following formula:
P = ηVI
where,
- P = Power = ?
- η = efficiency = 90 % = 0.9
- I = current = 38 A
- V = potential difference = 220 V
Therefore,
P = (0.9)(38 A)(220 V)
P = 7524 watt
converting this to horsepower:
P = (7524 watt)()
P = 10.08 hp

Answer:
Attached below is the Radial power circuit arrangement
Explanation:
Radial power circuit arrangement is done in a way that a single cable starts from the fuse box and connects to all the outlet socket contained in the circuit also the cable contains wires ( live , neutral and earth )
The advantage of a radial power circuit arrangement is that it enables easy identification of electrical faults on the circuit.
