How many watt in 5 amp switch normally use in home?
The switch will use no wattage whatsoever. The load on that switch is what uses power. If you know the load is 5 amps then 5 amps at 120 volts is 600 watts.
What is the output wattage of an iPod charger?
A typical iPod uses 12 v at 1 amp, and with the adaptor for 110/220 v the total consumption is about 20 W.
How much is 2 watts?
There are no "watts" in 2.5 volts. Wattage is the result when you multiply volts times amps. You cannot answer the question with only one quantity (in this case 2.5 volts). If you have 1 amp and 2.5 volts, they you would have 2.5 watts. If you had 2 amps and 2.5 volts, they you would have 5 watts. The formula is Volts X Amps = Watts.
How many amps does a 12 volt 600 watt transformer use at 120 volts?
A transformer does not use, it transforms voltage from one value to another. The output amperage is governed by the connected load. If the load wattage is higher than the wattage rating of the transformer then either the primary or secondary fuse will blow or the transformer will burn up if the fusing is of the wrong sizing. The maximum primary amperage can be found by using the following equation, Amps = Watts/Volts, A = W/E = 600/120 = 5 amps. The same equation is used for the calculating the maximum secondary amperage, A = W/E = 600/12 = 50 amps.
How much current would a 5-kW heater draw with 230 volts?
The formula you are looking for is I = W/E, Amps = Watts/Volts. Amps = 5000/230 =21.7 amps. The wire size to run this heater would be a #10 copper conductor. The supply breaker would be a two pole 30 amp breaker.
What is the current in an ac circuit with 120-volts and a 60 -watt light bulb?
Current or amperage, is wattage divided by voltage. 60 / 120 = .5 amp.

What is the wattage of 115 volts and 5 amps?
Ohms law will tell you watts equals volts times amps: 115 x 5 = 575
Is it okay to use a 5 volts amp DC power supply with a device that says it needs 5 volts 2 amp?
It looks like the crucial number was left out of the question, between the words "volt ... amp DC". If the device says it needs 5 volts at 2 amp, it will run safely on any DC power supply rated at 5 volts and (2 or more) amps.
What is the output wattage of an iPod charger?
A typical iPod uses 12 v at 1 amp, and with the adaptor for 110/220 v the total consumption is about 20 W.
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.

What is the maximum wattage for 5 amp fuse?
The 5 amp fuse has many wattages that it can protect. It depends on the voltage of the circuit that the fuse is protecting. Use the following formula, Watts = Volts x Amps. For example 120 volts x 5 amps = 600 watts, 240 volts x 5 amps = 1200 watts, 480 volts x 5 amps = 2400 watts and 600 volts x 5 amps = 3000 watts.
How do you wire the lights to a 240V panel if you have 5 MH light fixtures that are rated for 110v208v230v277v of which have 2 wires coming from them and what size breaker is needed for all?
you would need to know the wattage of each lamp. multiply the lamp wattage x 5 = total watts divide the total wattage / 230 volts (or the voltage you will connect to)= amps example: 250 watts x 5= 1250 watts 1250 watts / 230 volts = 5.43 amps
