The formula for I²R loss, also known as resistive or copper loss, is expressed as:
[ text{Loss} = I^2 times R ]
where:
– ( text{Loss} ) is the power loss in watts (W),
– ( I ) is the current flowing through the conductor in amperes (A),
– ( R ) is the resistance of the conductor in ohms (Ω).
Answer: d
Explanation: The number of conductors and copper loss in each conductor is first
calculated. On substitution the I2R loss is obtained.
