What else can I help you with?
How much current will pass through single phase?
The current is limited by the fuse or circuit breaker.
Why phase current is equal to line current in star connection?
Because it is the same current, as you can determine by examining a circuit diagram of a star connection.
A capacitive device in a single phase ac circuit causes the current waves to?
Lead the voltage waves
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
In a 240 volt single phase circuit A phase is 4000 watts B phase is 7000 watts what is the neutral load?
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
Why to use 3 phase instead of single phase in industry?
Two phase and three phase electrical circuit have more energy in them, in a given time (cycle) that single phase. I believe two phase had twice the energy as a single phase circuit, and 3 phase has 3 time the energy.You can get the same energy (H.P., work) done with a single phase circuit (motor), but you'd need to draw more current (twice the current compared to a 2 phase circuit.) If you examin a motor that can be wired either 110, or 220 VAC, you'll note that the current for the 110 VAC is twice the current for the 220 VAC wiring.Two and 3 phase circuits allow motors or other high power industrial devices to pack more horsepower into the device, without drawing excessive amount of current. Larger current would demand larger wiring, breakers, etc. driving up costs.AnswerFor a given load, a three-phase supply requires around 75% of the volume of copper compared to a single phase supply and, therefore, is more economical. Also, three-phase motors are more compact, and are self-starting. Two-phase supplies are archaic and unlikely to be seen these days.
What is the phase angle between voltage and current in a purely resistive circuit?
The phase angle between voltage and current in a purely resistive circuit is zero. Voltage and current are in phase with each other.
What is the purpose of conducting sc and oc test of single phase transformer?
The purpose of conducting sc (short circuit) and oc (open circuit) tests on a single-phase transformer is to determine its equivalent circuit parameters, such as the winding resistance, leakage reactance, and magnetizing reactance. These tests help to evaluate the transformer's performance and efficiency under various operating conditions.
How many amount of current flow in spark use 230 volt single phase supply?
It is limited by the size of the fuse in the circuit.
Compare the phase relationship between the voltage and current in a purely resistive circuit and an RL circuit?
In a pure resistive circuit the voltage and current are in phase. In an inductive circuit they are fro zero to 180 degrees out of phase. If they are in phase the Power Factor is 1 and 180 degrees the PF is zero. The exact amount of the phase difference depends on the specific circuit.
Why you use upf wattmeter for short circuit test on load test on single phase transformer?
If, by 'upf', you mean 'unity power factor', then allwattmeters measure the in-phase component of the load current, so the term is quiet unnecessary.A short-circuit test is used to determine the (true) power loss in the transformer, which is exactly what a wattmeter measures
Is the neutral conductor of a two wire single phase circuit considered a current carrying conductor?
Sure. In a two-wire circuit, both wires carry equal currents.
