A single phase motor connected to 415 V, 50 Hz supply takes 30 A at a power factor of 0.7 lagging. Calculate the capacitance required in parallel with the motor to raise the power factor to 0.9 lagging.
In single phase energy meter, Current coil is made up from thick wire having few no. of turns. Pressure coil is made up from thin wire having more no. of turns.
Volatility is a statistical measure of the dispersion of returns for a given security or market index. Analysis of a mineral oil sample for volatile compounds provides an indication of whether a fault or significant degradation has occurred.
