For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
nearly 10 amps on single phase 240 volts
As heater motors age, they tend to draw more amps than they should. Yours is probably drawing too much amperage causing the switch to heat up. Remedy is to replace the heater motor and possibly the switch as the terminals get hot and oxidize.
Maybe, or maybe not. Depends upon the wattage or amperage draw. At 120 volts and 150 watts, you can draw about 1.2 amps. Probably not enough for a newer laptop, but may power an older one fine. A 300 or 600 watt inverter can be bought on eBay for about 30 bucks.
It depends on the load and the voltage. In an automobile, a battery will typically have a voltage of about 12 Volts. If the engine is not running and you turn on the lights, the lights will start drawing current from the battery and the voltage will drop by a volt or so, depending on how strong a charge the battery has. An alternator will produce in the neighborhood of 15 Volts. If it is trying to push current into a system with a fully charged battery, it will only be able to push a few amps. If the voltage in the battery drops, the alternator will be able to push more amps. A completely dead battery will draw the most current (amps).
The question doesn't make sense. Watts are the product of volts and amps so you could have 1 V with a current of 1 amp = 1 watt or 10V and a current of 0.1 amps = 1 watt or 100V and a current of 0.01 amps = 1 watt etc.
It depends on the voltage-- I think at 110v it's 4 amps per hp
Current (amps)=Watts/Volts =2000/120 =16.75 =16.75 amps
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
Amps * Volts = Watts So, Watts / Volts = Amps 2000 / 240 = 8.333 Amps You should run the circuit on a two pole 15 Amp breaker, using 14 AWG, 2 conductor (plus ground) wire, just so you have a little safety factor in the circuit size.
10 Amps. Amps=Watts/Volts
The formula you are looking for is I = W/E.
9000 BTU/hour is equivalent to 2300 watts so the heater will draw 10 amps on 230 volts.
The electric heater will have power rated in Watts. The Amps it will draw depends on the voltage system you are using. Can be calculated by formula I (Amps) = P / V In the USA with 110V system a 2400W heater will draw 2400 Watts / 110 Volts = 21.8 Amps In Australia with a 230 V system a 2400W heater will draw 2400 Watts / 230 Volts = 10.4 Amps
At 120 Volts you would draw about 42 amps. At 240 Volts it would be about 21 amps. For 120 Volts you would need 6 AWG and for 240 Volts you would need 10 AWG.
Each baseboard heater will draw a little over 4 amps at 120 volts or 2 Amps at 240 volts. The total number of baseboards on a circuit will draw the sum of these amps. Keep the load under 80% of the amperage rating of the breaker.
There are zero amps in 1000 watts. Watts are the product of amps x volts or I = W/E, watts divided by voltage. As you can see, that if no voltage is stated no amperage can be given. Once you find the voltage of the heater then use the following equation, Amps = Watts/Volts to find the current draw of the 1000 watt heater.
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.
The watts is the volts times the amps So 208 x 50 watts, or 10.4 kW.
