Question
A transformer takes 5.17 kW at a power factor of 0.85 when connected to a. 2.3kV distribution circuit. What is the current in amp?
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.
