What is a synchronous rectifier?
a circuit that emulates a diode,allowing current to pass in one direction but not the other without the losses associated with the junction
What are the effect of hunting in synchronous motor?
1.it can lead to loss of synchronism. 2.the machine losses increases 3.temperature of the machine rises . 4.it can increases the possibility of resonance.
What is the condition for maximum efficiency of a DC machine?
The condition for maximum efficiency of a d.c. machine is that VARIABLE LOSSES must be equal to CONSTANT LOSSES i.e., variable losses = constant losses..
Why there are no losses in DC transmission?
There are losses in d.c. transmission lines, due to their resistance. But there are no reactive losses. So, d.c. transmission lines have less losses in comparison to an equivalent a.c. transmission line.
Explain the power flow diagram of induction motor?
The input power, Pin, is reduced by different loss sources in the system. These reductions are the difference between input power & output power. The losses are: PSCL: Stator copper losses, or I2R losses Pcore: Core losses PRCL: Rotor copper losses PF&W: Friction & windage losses Pmisc: miscellaneous losses All of these losses reduce the input power. The output power is the input power minus all of the losses. Pout = Pin - PSCL - Pcore - PRCL - PF&W - Pmisc
What factors contribute to the optimization of Peltier efficiency in thermoelectric devices?
Factors that contribute to the optimization of Peltier efficiency in thermoelectric devices include the choice of materials with high thermoelectric properties, proper design and engineering of the device to minimize heat losses, and operating the device at optimal temperature differentials.
What is a synchronous rectifier?

What is the economic function of profits and losses?
The economic function of profits and losses is to determine the performance of a company. This is what will contribute to the overall measure of the economy in a region.
Are the friction losses of an induction machine linear?
No, the friction losses of an induction machine are not linear. These losses are typically influenced by factors such as speed, load, and temperature, which can make the relationship between friction losses and operating conditions non-linear.
How did buying stocks on credit contribute to the Great Depression?
When stock prices fell, people did not have the money to cover their losses.

What are the losses for under ground armored cable?
Losses for underground armored cable can include resistance losses due to the resistance of the conductors, dielectric losses due to the insulating material, and skin effect losses at high frequencies. Additionally, there can be losses due to environmental factors like moisture or temperature variations impacting the cable's performance.
Are the frictional losses of the induction machine linear?
No, the frictional losses of an induction machine are not linear. Friction losses increase with speed and are affected by factors such as temperature, lubrication, and surface finish. These losses are typically represented as a quadratic function of speed in machine modeling and analysis.
Calculate copper losses at 75c?
Copper Loss at 75 C = Copper Loss at Ambient Temperature C * (310/(235+Ambient Temperature C))
What factors cause losses in ferrous raceways in an AC circuit?
Losses in ferrous raceways in an AC circuit are caused by factors such as eddy currents induced by varying magnetic fields, skin effect which leads to increased resistance at high frequencies, and hysteresis losses due to the magnetic properties of the ferrous material. These losses contribute to decreased efficiency and can lead to heating of the raceway.
What is the temperature at which a liquid changes to a solid called is there a gain or a loss of energy?
Such a temperature is known as Freezing point of the liquid, during the freezing process the system losses the energy.
