How electrical power is transmitted from power plan to the consumer?
electrical power from the power plant to consumer goes through the transmission & distribution system, first we transmit the high voltage power from the power plant to sub station in sub station we step down the voltage according to need & distribute it to the demand.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
How many DC volts of solar power would it take to suppy a home 3500kWh?
Power = voltage * current. Without current, relating voltage to power is meaningless. One thing I can say is the voltage should be dictated by the amount of losses that is acceptable - the cabling you use to transfer the power to your home will have a specific resistance per unit length, which is unchanging. If you choose to use a low voltage, you will in turn use a fairly high current to transfer the energy you want. The power lost in the cable will be P = R * I^2. This loss can become significant, dictating a higher voltage.
How do power cords differ?
Power cords have different voltage rate, example 7A/125V cord can hold much voltage than 3A/125V. The higher the current flow can melt the lower type of power cord that is dangerous and can cause fire. Base on my knowledge there are different types of power cords according to the ampere and voltage needed.
What is the formula for power delivered by a voltage source?
Power is voltage times current.
What Is necessary to convert higher voltage power to low voltage power?
A transformer
What is the relationship between voltage power and current?
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
Why are transformers necessary?
Transformers are necessary to stepup or stepdown voltage levels so that transmission of power is convenient. without stepup/stepdown voltage level according to our requirement losses will be very high and transmission and usage of power is not feasible.
What is the kva for 138kv?
KVA is a measurement of power; kV is a measurement of voltage. You're asking "What is the power for voltage?", which makes no sense. Power = Voltage times current.
How do i fine an expression for power that involves only current and voltage?
You do not need ohm's law to relate power to current and voltage. Power is current times voltage. If you know current and voltage, you do not need to know resistance.
What voltage should you have your power pack when tattooing?
What voltage should you you have your power box on when tattooing
How is power and voltage related?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
