Read Answers (3) | Asked by : Amit Sinha 1. what is the different between CGS system and MKS system? 2. When we connect the capacitor Banks in Series with the circuit 3. What is the difference between Earthing & grounding 4. how much voltage Latest Answer : When the current lead in the circuit use the capacitor in series. ... generally we are using 4 core or 3.5 core cable for power supply ,in this practice we are connecting three different phase R,Y,B and Neutral to our 4 core or 3.5 core cable,but for our termination conveniences Latest Answer : Due to use of bundled conductors it will give rise to sheath losses. Which will increase the temperature to overcome this use cross bounding. In overhead lines use both cross bounding and transposition to get a better result. ... Read Answers (2) | Asked by : jatin patel What do you mean power factor?What is the use of Power Factor? Latest Answer : We know power factor(ie.Current lags or leads behind voltage by some angle,and cos of that angle is power factor)...If the power factor drops below 1,the current consumed increases with the decrease in power factor...(for instance,load with pf 0.2 consumes ... What is Power Factor? How it is calculated? Latest Answer : Power factor is the ratio between Real power to the Apparent power. It indicates, how much power was actually utilised by the present system. For example, if any system had a power factor of 0.8 means, it can be able to utilise only the 80% of the Power ... Can we measure reactive power by using only a single wattmeter? If Yes, How? Latest Answer : We can't measure the reactive power by using wattmeter. ... The power is -ve for the first 2ms and then it will -ve What will be the P.F. Angel? What is mean by reactive power? How it is generated? Latest Answer : We know reactance (hypothetical resistance) which reduce the supply voltage by opposite flowing induced emf. This power loss due to reactance is known as reactive power. This power is not useful power. It is a waste. However it is useful in determining ... Wattmeter has two coils in it-the current coil & pressure coil, why is the pressure coil so named? How is the power being measured by the Wattmeter? Latest Answer : Current coil means it measure current of circuit & pressure coil means it measure voltage, when current coil is connected series, pressure coil connected parallel in one circuit ,as P=V*I*cosØ,
So we have V, I, & Ø=[1/tan(V/I)],
Now the power is being ...
