How many volts it takes to cause a current of 1.95 amps to exist in a 200 watt lamp?

The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.

250 watts is how many amps?

Depends on the voltage. AMPS X VOLTS = WATTS 250 Watts at 12 V would be about 21 Amps, while 250 watts at 120 volts would be 2.1 amps.


How many amps are in 2000 watts using 110 volts?

To calculate the amps, you can use the formula: Amps = Watts / Volts. So, for 2000 watts and 110 volts, 2000 watts / 110 volts equals approximately 18.18 amps.


How many watts is equal to 4.3 amps at 230 volts?

In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts


5000 watts equal how many amps?

There is no direct conversion between the two. You need to know voltage to calculate amps. This is the equation: P = V * I Where: P = Watts V = Volts I = Amps


How many amps is 3000 watts?

Amperage (coulombs/sec sort of like volume) and wattage (power) are independent of each other if you know the voltage you can calculate amps but they are not the same thing. 3000 watts/X volts=amps ex. 3000 watts/110v=27.28 amps


How do you calculate the current?

If the wattage of a load is known then the current can be calculated. Watts equals amps times volts. You would use the following formula, Amps = Watts/Volts.


Calculate watts from volts and amps?

Just multiply. (Note, this assumes no phase difference.) <<>> The formula you are looking for is W = I x E. Watts = Amps x Volts.
