Input Power of DC Motor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Input Power = Supply Voltage*Armature Current
P_in = V_s*I_a
This formula uses 3 Variables

Variables Used

Input Power - (Measured in Watt) - Input Power refers to the power input required to rotate the armature of the dc machine, which in turn generates electrical/mechanical power. The input power is provided by an external source.
Supply Voltage - (Measured in Volt) - Supply Voltage refers to the voltage developed at the supply terminal of a generator.
Armature Current - (Measured in Ampere) - Armature Current is defined as the current developed in the armature of an electrical DC generator due to movement of rotor.

STEP 1: Convert Input(s) to Base Unit

Supply Voltage: 240 Volt --> 240 Volt No Conversion Required
Armature Current: 0.75 Ampere --> 0.75 Ampere No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_in = V_s*I_a --> 240*0.75

Evaluating ... ...

P_in = 180

STEP 3: Convert Result to Output's Unit

180 Watt --> No Conversion Required

FINAL ANSWER

180 Watt <-- Input Power

(Calculation completed in 00.004 seconds)
