What else can I help you with?
A toaster draws 8 A of current with a voltage of 120 V?
The voltage is the main power of a toaster!! but if the current flow is low the heat of the toaster is less heat that you expect, the 8 A is right for your toaster!!!
What is the efficiency of a 172.5Watt heater which draws 2A from a domestic supply?
Heaters have an efficiency around 99%.
Are electric baseboard heaters efficient?
Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. Which ever device draws the higher amperage will be the one that uses more electricity! Hence the 240 watt heater draw less amps even though it uses more watts: Volts Watts/Electical Current Amps/Power example heater 240 volt draws 2000/1000 watts - but uses 8.3/4.2 amps example heater 120 volt draws 1500/750 watts - but uses 12.5/6.3 amps
What size wire 100 kva transformer?
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
What is the resistance of a clothes iron that draws a current of 12A at 120V?
By Ohm's Law Voltage = Current x Resistance R = V / I = 120 / 12 = 10 Ohms
Does increasing the voltage to an electric heater increase the amperage it draws?
It will increase the current since the water heater is made of a heating element and which is resistive in nature. Ohms law states that V=IR where V is the voltage, I the current and R the resistance. Now the resistance will always remain constant. Thus, when the voltage is increased, the current will also increase.
How many amps does a block heater draw?
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
How many amps is block heater for 2500ram 1999?
Find the block heater and look for the nameplate on it. It will be in watts. Use the following equation to find the amperage that it draws. Amps = Watts/Volts. The voltage to use for the truck will be 12 volts.
What is the voltage across a device that draws 2A and dissipates 12w?
The voltage across a DC device that draws 2A and consumes 12Wh/h is 12/2 or six volts.
A toaster draws 8 A of current with a voltage of 120 V?
The voltage is the main power of a toaster!! but if the current flow is low the heat of the toaster is less heat that you expect, the 8 A is right for your toaster!!!
A heater draws 8.70 amps on a 110 volt line What is its wattage rating?
Power = Voltage x Current P=V.I Power (in Watts) = 110V x 8.70A = 957W (Appx. 1kW) - Neeraj Sharma
How many amps will a 230 vac 3500 watts heater draw?
Since power = voltage * current we have current=power/voltage so 3500 watts/230 volts = about 15.218 amperes in a heater using a resistance to generate heat. This should be valid even though the "230 vac" indicates that it is an AC circuit and not a DC circuit.
A water heater draws 40A from a 120V power source in 10m away What is the minimum cross section of the wire that can be used if the voltage applied to the heater is not lower than 115V?
To maintain a voltage drop of less than 5V over the 10m distance at a current of 40A, you would need a wire with a minimum cross section of 6 AWG. This size of wire will help ensure that the voltage applied to the heater remains not lower than 115V, taking into account voltage drop considerations due to the length and current draw.
What is the efficiency of a 172.5Watt heater which draws 2A from a domestic supply?
Heaters have an efficiency around 99%.
A video monitor draws 1.5 A at a voltage of 150 V. What is the power rating of the monitor?
225W
If electric heater works on 115 V and draws 3 A of current how much power does it use?
The formula you are looking for is W = I x E.
How do you calculate the resistance of a heater element that's uses 220v and draws 11amps?
The equation you are looking for is R = E/I.
