What else can I help you with?
What would be the voltage suplied to each circuit if three circuits are connected in parallel with a power supply of 30 volts?
30 volts.
What is percent of power loss at 415 volts against 11000 volts?
Power = voltage times current, and the power loss is the loss in the line, I^2 * R. At 11,000 volts, the current will be (11,000 / 415 = ) 3.77% of what it is at 415 volts. So the power loss in the line at 11,000 volts will be (3.77% ^2 = ) .14% of what it is at 415 volts.
How do you find the current draw of an electrical circuit if you do not know the voltage and wattage of the device?
Basically if you know the Voltage supply and the power used by an appliance then you use the formula for power which is Power = Volts x Amps. Rearrange so Amps (current) = Power / Volts If power was 2400 Watts and Volts was 240 the Current would be 2400 / 240 = 10 Amps
Unit of electric power determined by muliplying volts times amperes?
Power=Volts x Amps Unit for power is watts
How many milliamps in 48.8 watts?
Milli amps is a measure of current whilst watt is a measure of power. The missing element is voltage as the formula is:- Power = Voltage * Amps ie power in Watts is the product of Volts (in Volts) times Amps (in Amps)
Would 120 volts 60Hz power tools work on 220 volts 50Hz?
No, the extra voltage will burn them out very quickly !
What would be the voltage suplied to each circuit if three circuits are connected in parallel with a power supply of 30 volts?
30 volts.
Which consumes more power 480 volts or 240 volts?
Voltage itself does not consume power; rather, power consumption is determined by the combination of voltage and current. If the power demand remains the same, a higher voltage system like 480 volts will require less current to deliver the same amount of power compared to a 240-volt system. So, in general, a 480-volt system would be more efficient in terms of power transmission compared to a 240-volt system.
Is 12 volts dc as powerful as 120 volts ac?
You get power by multiplying the amperes and the voltage. 12V, 10A dc would give the same power as 120V, 1A ac.
How can you calculate current when you have volts power?
Divide Watts by Volts ; this gives you Amps.
How many volts are in a power point?
230 volts
How many watts in 10 amps 240 volts supply?
The power can be calculated using the formula P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps. Plugging in 240 volts and 10 amps, the power would be 2400 watts.
How do you grade up micro volts to volts which can operate any small devices?
The voltage can be changed by a transformer, but the power remains constant. So if you have a supply of 1 microvolt, it would have to supply 1 million amps to give a power of 1 watt (power = volts times amps).
What is percent of power loss at 415 volts against 11000 volts?
Power = voltage times current, and the power loss is the loss in the line, I^2 * R. At 11,000 volts, the current will be (11,000 / 415 = ) 3.77% of what it is at 415 volts. So the power loss in the line at 11,000 volts will be (3.77% ^2 = ) .14% of what it is at 415 volts.
Can a 220 volts ac fan run in a 12 volts battery?
No, a 220 volts AC fan cannot run directly from a 12 volts battery. The fan requires a much higher voltage to operate efficiently. You would need a power inverter to convert the 12 volts from the battery to 220 volts AC to power the fan.
Can you use 5 volts 1.2 amp power supply on 5 volts 3.0 amp device?
No you can not. The power supply output of 1.2 amps is under sized. You would need to have a power supply of 3 amps or larger.
How do you find the current draw of an electrical circuit if you do not know the voltage and wattage of the device?
Basically if you know the Voltage supply and the power used by an appliance then you use the formula for power which is Power = Volts x Amps. Rearrange so Amps (current) = Power / Volts If power was 2400 Watts and Volts was 240 the Current would be 2400 / 240 = 10 Amps
