A THHN conductor will have a 60˚C termination on one end and a 75˚C termination on the other, which ampacity column will be used?

Conductor with higher temperature ratings, provide the ampacity is determined based on the 60°C ampacity of the conductor.

Who started the daily newspaper 'National Herald' in 1938?

Choose the word which expresses nearly the opposite meaning of the given word "WHIMSICAL"

The expression for voltage regulation of a short transmission line for leading power factor is given by: ____, where, 'I' is the line current, 'V_r' is the receiving end voltage, 'R' is the line resitance and 'X' is the line reactance.

For lagging power factor = (IR*cosφ + IXsinφ)/V_r
For leading power factor = (IR*cosφ - IXsinφ)/V_r
Zero voltage regulation occurs on leading power factor only.
