Assuming this is a WYE connected system: (Most commercial/industrial services are) Your question answered it: 480 volts. The phase to phase voltage on this system is 480 volts and the phase to ground voltage is 277 volts.
Answer
The 'leads' you refer to are more-properly called 'lines', and the voltage between any pair is called a 'line voltage' (not a 'phase voltage', as stated in the original answer). The rated voltages of three-phase systems, regardless of whether they are three-wire (delta) systems or four-wire (star/wye) systems are always quoted in terms of their 'line voltages'. So, to answer your question, the line voltage ('voltage between leads' ) of your three-phase system is 480 V. If your system is a four-wire star/wye system, then the phase voltage voltage, or 'line-to-neutral' (not 'phase to ground') voltage is the line voltage divided by 1.732, i.e. 277 V.
In 480 volt 3-phase power supplies, each single phase lead has a voltage of 277 volts from lead to ground. There are 277 * square root of 3 (1.73) = 480 volts phase to phase.
Voltage will be same in all branches. Voltage= Current * Total Resistance
Power factor is the ratio of true power to apparent power -if you refer to the so-called 'power triangle', these correspond to the adjacent and hypotenuse of a right-angled triangle. The cosine of the angle between them is the ratio of hypotenuse (apparent power) to adjacent (true power). As the power triangle is derived from the voltage/current phasor diagram, this is exactly the same angle as that between load current and supply voltage.
IC 7806 is the voltage regulator that gives 6V dc voltage from 230V ac power supply. It is used to give power supply to the IC which operates on 6V.
The word "developed" is slightly odd in this context. If the power supply provides a current to some instrument or device, the power supplied is the voltage multiplied by the current. The power supply will also consume some power itself to do this job. The total power consumed (provided to the power supply) equals the input current multiplied by the input voltage.
By using a voltage divider, that is two resistors of the same value in series across the DC supply. Half of the supply voltage will be at the point where the two resistors is connected. But how much wattage of those resistors is also an issue.
Yes. Depending on the design, the power supply can provide any voltage desired.
You need to convert the voltage if your appliance requires less voltage than you power supply. example: appliances is 110V and power supply is 220V.
AVR means Automatic Voltage Regulator. It automatically maintains a constant voltage level. AVR may be a separate device or a part of powet supply.
The current in a circuit, expressed in milliamperes, is1,000 x (battery or power supply voltage)/(resistance connected between the power supply terminals)If you increase the voltage of the battery or power supply, the current in the circuitincreases proportionally, at least until something in the circuit gets hot, melts, fuses,and opens the circuit.
The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and packaging will state voltage recommended for the product.

Obtain a power supply that has the correct output voltage that you need.
Yes of course!! 10 kva electrical power is 10 kva electrical power either it would be three phase or single phase. But other factors i.e. current, voltage changes accordingly. Actually this question is quit confusable. Because in 3phase system, if each phase gives 10kva power (single phase power = 10 kva) then 3 phase power will be 10 X 3 = 30 Kva If we go leteratualy towasrds the question, then the asnwer will be - No. becasue 10 kva supply to 3 phase load will be 3phase supply(i.e440V) & 10kva supply to single phase load will be single supply (i.e 250V).
f your supply is a Y connected transformer (4 wires COM) with a phase to phase voltage of 380 volts (voltage between any two of the hot wires) , utilizing a true Y connection to your load (connections of one hot lead and neutral for each phase to your load will give a voltage of 380 รท sqrt 3 = 380 รท 1.732 = 220 volts.
Yes.
In principle a generator is the same as a motor. In a dc motor the voltage generated by the rotating armature is slightly less than the supply voltage which causes power to flow in from the supply. If an engine is then coupled to the shaft causing it to rotate faster, then it generates more voltage and power flows back into the supply. That is how a motor becomes a generator.
