The difference in the power required by the motor at start up and at operating speed is 9778.57
This is defined as the rate in which energy is consumed. Electrical power is expressed mathematically as:
Power (P) = voltage (V) × current (I)
P = IV
Power = square voltage (V²) / resistance ®
P = V² / R
P = V² / R
P₁ = 62² / 0.14
P₁ = 27457.14 watts
P = V² / R
P₂ = 37² / 0.14
P₂ = 9778.57 watts
Difference = P₁ - P₂
Difference in power = 27457.14 - 9778.57
Difference in power = 17678.57 watts
