What is the formula of 2 phase power?
The formula which are needed for making of a single phase transformeri.e o/p voltage,watt,current,turn,core size,coil number,bobin size etc
What is the formula for Kirchoff's current for parallel circuits?
Kirchoffs's current law states that the sum of all the currents flowing out of any point is equal to zero. In other words, the current flowing in is equal to the current flowing out.In the case of a parallel circuit, this means that if a single current branches into two or more parallel branches, then the sum of the currents in the parallel branches must be equal to the original current before it branched.
How should I calculate this. A single phase transformer is rated at 99kVA The primary voltage is 6.6kV and the secondary voltage is 220V Assume no losses and calculate The full load primary current?
First find the ratio of the transformer. 6600/220 volts. Second find the secondary current, I = W/E, 99000/220. Third divide the secondary current by the transformer ratio. The answer will be the primary current. To check your answer (W (or VA) = V x A) multiply the primary current times the primary voltage and the secondary current times the secondary voltage and they should both equal the transformer's kVA.
How do you calculate cable size for 50 hp?
just apply the formula :-p=v*i*cos(angle);now you have the power rating,load so in turn power factor so you can easily calculate the value of current.with the help of current you can chose the cable available in the market either the aluminum or copper wiresatendra.svnit@gmail.com
How do you calculate the size of cable for 1000kw generator?
To calculate the size of cable for a 1000kW generator, you need to consider the generator's voltage and the distance the cable will run. You will need to calculate the current the generator will draw at full load using the formula: Current (A) = Power (W) / (Voltage (V) x Power Factor). Once you have the current value, you can use it to determine the appropriate cable size based on the current carrying capacity of different cable types, factoring in voltage drop considerations for the distance the cable will run.
