Solution

To find the current, we can use the formula for power which is P = VIcosθ, where P is power, V is voltage, I is current, and cosθ is the power factor.

Given: P = 5.17 kW = 5170 W (converting kilowatts to watts) V = 2.3 kV = 2300 V (converting kilovolts to volts) cosθ (power factor) = 0.85

We can rearrange the formula to solve for I: I = P / (Vcosθ)

Substituting the given values: I = 5170 W / (2300 V * 0.85)

Calculating the above expression will give us the current in amperes.
