Answer:
W= F × d
W= 2kn × 3.6
W= 7.2 J
Work is measured in Joules!
Answer:
The percentage power lost in the transmission line if the voltage not stepped up is 50%.
Explanation:
Given that,
Current = 60 A
Voltage = 120 V
Resistance = 1.0 ohm
We need to calculate the power
Using formula of power

Where,I =current
V = voltage
Put the value into the formula


We need to calculate the percentage power lost in the transmission line
If the voltage is not stepped up
Then, the power loss

Put the value into the formula


The percentage power loss P''


Hence, The percentage power lost in the transmission line if the voltage not stepped up is 50%.
