Fuses are rated in Amps. Although the physical size of a fuse is to do with volts; the further the terminals are apart the less likelihood there is of 'sparkover' between them.

What size wire do you need for 650 watts?

To answer this question a voltage needs to be stated. Wire is sized by the amount of amperage the load takes. W = Amps x Volts. Amps = 650/ volts.


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 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.


If voltage is 12 volts and ohms is 0.5 how many amps in circuit?

Ohm's law: Volts = Amps * Ohms, or Amps = Volts / Ohms 12 volts / 0.5 ohms = 24 amps


What does 1500 watts equal in amps at 120 volts?

To convert watts to amps at 120 volts, use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the calculation would be: 1500 watts / 120 volts = 12.5 amps.


4 volts is a many watts?

4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts... See Ohms Law: Watts = Volts x Amps If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts. If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.


Using 120 volts at 12 amps is the same power as what amps at 220 volts?

6 amps.


How many amps at 12 volts equals 16 amps at 120 volts?

160 amps at 12v.


How many amps at 120 volts equals 16 amps at 12 volts?

160 amps at 12v.


How many amp is 115 volts?

To determine how many amps are in 115 volts, you need to know the power (in watts) being used. The relationship between volts, amps, and watts is given by the formula: Watts = Volts × Amps. Therefore, to find the amps, you can rearrange the formula: Amps = Watts / Volts. For example, if you have a device that uses 1150 watts, you would have 10 amps at 115 volts (1150 watts ÷ 115 volts = 10 amps).


200 watts to amps 12v?

To convert watts to amps, you can use the formula: Amps = Watts / Volts. In this case, to convert 200 watts at 12 volts to amps, it would be: 200 watts / 12 volts = 16.67 amps. So, 200 watts at 12 volts is approximately 16.67 amps.


How many amps are in ohms?

It's not that simple. The basic formula is Volts / Ohms = Amps. For 30 Volts you'd get 0.5 Amps, for 60 Volts you'd get 1 Amp, for 120 Volts you'd get 2 Amps.
