Using the formula P = IV (power = current x voltage), you can rearrange it to solve for current: I = P/V. Plugging in the values, the current would be 0.25 amps (30 watts / 120 volts = 0.25 amps).

How many watts are in 30 volts?

To calculate the power in watts, you will also need to know the current in amperes. The formula to calculate power is P (watts) = V (volts) x I (amperes). If you only have the voltage (30 volts) and not the current, you cannot determine the power in watts.


Can you join a 6000w cooker hop with a 30 amp junction box?

30 amps at 120 volts is 3600 watts. 30 amps at 240 volts is 7200 watts.


How many amps are in 280 watts with 120 volts?

W = Amps times Volts. A = W/V, A = 300/120 = 2.5 amps


How many amps in 3500 watts with 120 volts?

That depends on the voltage, but the residential standard is 240 volt. At that voltage you sit at around 15 amps, however it MUST be on a 20 amp circuit for national (US) or Canadian electrical code, as you can only load your circuit to 80% of it's capacity.


HoW many amp is 300 watts?

As asked, the question cannot be answered. At 1 volt, 300 Watts = 300 Amps. At 10 volts, 300 Watts = 30 Amps. At 100 volts, 300 Watts = 3 Amps. At 120 volts, 300 Watts = 2.5 Amps. At 240 volts, 300 Watts = 1.25 Amps. To calculate the relationship between Amps, Volts and Watts, use the formula: Watts = Amps * volts


At 12 volts how many watts is 30 amps?

Watts is volts times amps, so 12 x 30 = 360 watts


If you have a 30 amp breaker how many watts can it use?

To answer this question a voltage must be given. Watts = Amps x Volts. <<>> Answer At 115 volts ac, 30 amps equals 3,450 watts.


A clock radio is rated as 30 W of power output If the radio also draws 30 W at 120 V which will the current draw be?

A clock is not a generator so it does not have any power output. If anything the clock could consume 30 watts of power in its operation. The formula you are looking for is I = W/E, Amps = Watts/Volts.


How many amps is 360 watts?

"Volt" is a unit of potential difference. "Joule" is a unit of energy. There is no direct conversion from one to the other. -- If a 2-ohm resistor is connected to a 5-volt battery, then the current through the resistor is volts/ohms = 2.5 amperes. -- The power supplied by the battery and dissipated by the resistor is (volts) x (current) = 12.5 watts. -- "12.5 watts" means "12.5 joules of energy every second".


How many watts can a 30 amp service deliver?

There is insufficient information to answer the question. Volts * Amps = Watts. If one assumes 240 Volts * 30 Amps you would have 7200 Watts (peak) available. But don't ever plan to use that amount of current for anything more than a few seconds.


Single phase 220 volts 2.6 kW how many amps?

You cannot convert 2.6 kw to amps with that information only. In order to convert watts to amps, you also need to know either current or voltage. This is because watts is volts times amps, and volts is current times resistance


How many amps for 120 volts?

As many as you want. It depends on the capacity of your supply. Let me break this down. Current or amps is what is drawn by a device or a load. For example, lets say you plug in a 1500 watt 120 volt space heater and turn it on. Now you want to know what kind of amperage is being drawn by this device. Take 1500 watts and divide 120 volts into it. The answer will be your amperage or current. The current draw would be 12.5 amps. (I know there are other people out there who say no no that is not entirely right. I know this. I do not wish to give a lesson in calculating impedance when this answer is close enough and is with in a safe range of accuracy. Just keeping it simple)Another fact that may be of interest to you is there is as much as a 8000 fault amp potential in the average 100 amp service panel. This means that if your two lines coming into your panel would short it would blow up. This is what is called an Arc Blast.
