What is the output power equation for the solar cell?
Latest Answer: p=Current per unit area x EMF ...
Explain what are Single and 2 Pole circuit breaker?
Can VFD step up to 60 Hz if it is designed to receive 50 Hz input?
What is the power factor?
Latest Answer: Power factor is the ratio of active power to apperant power. for better energy efficiency it should be unity. ...
What are the problems that may occur if a transformer frame is made of concrete instead of metal?
What would happen if a transformer is made to operate at 60Hz instead of 50Hz ?
Latest Answer: In transformer eddy current lossesPe=Kv^2 it is not dependent on frequency so only hyteresis losses will get affectedPh=KfB^x ...
What is meant by Floting Earth? What will happen if we use regular earthing instead of floting earth and Where do we have to use only floting earth.
Latest Answer: Floating Earth used in High Voltage equipment for high voltage Pit-Earth Test carried out for Transformer, Generator, Compressor, cables etc. for checking the condition of moister & dryness of the cable. ...
Why We should use only Fuse units in APFC Panel circuit instead of ACB/MCCB/MCB?
Explain why the secondary terminal of current transformer should not be lift open circuited.
Latest Answer: If the secondary of CT is left opened, there wont be any current flow in secondary thus increasing iron loss (eddy,hysteresis). This results in wastage of power in form of heat in th core. It also leads to saturation of the core. ...
Why there is 220v in 1-phase but 440v in 3-phase?
Latest Answer: The output of generator having 120 degree phaseshift. Ever time the instantaneous magntiude will be root 3 times the phase voltage. The magnitude will be same. While measuring we are considering the two phases which is maximum. ...
