The watts is the volts times the amps
So 208 x 50 watts, or 10.4 kW.

What is the kilowatt output of an electric heater that has an ampere draw of 50 and a voltage source of 240 volts?
At 240 v and 50 amps the power is 12 kW because 240x50 is 12,000.
What is the kilowatt output of an electric heater that has an ampere draw of 50 amps and a voltage source of 208 volts?
The formula you are looking for is W = A x V. Then divide the wattage figure by 1000 to change watts to kilowatts.
How does a resistor help an electric heater?
An electric heater is a resistor. It is a resistor with the right amount of resistance to take the required amount of power at the specified voltage. With a case to put it in and louvres to let the warm air circulate, that is a heater.Resistance in ohms is equal to the voltage-squared and divided by the watts.
How a electric heater works 2 references?
An electric heater is a resistor that dissipates electric power when a voltage is connected across it and a current flows through it. The amount of power in watts is equal to the voltage times the current in amps. Typical space heaters for use in the home are 1.5 kW to 3 kW to heat a single room.
A 50 gallon electric water heater that uses 2 elements is normally what voltage?
In North America 240 volts.

What is the voltage of a small electric heater if the heater is drawing 12 amperes and has a resistance of 10 ohms?
Voltage is current times resistance, 1.2 x 110 = 132 volts.
How many watts does an electric heater use?
An electric heater is an electric appliance that convert electrical energy in to heat. Working principle of an electric heater as per "Joule heating theory" When electric current passes through a resistor that electric energy convert to heat (best and simple example is a spring type heating element). When Voltage applied both end of a wire/spring type Resistance wire, voltage flow and this voltage help that wire to heat up and convert in to heat. A Resistance wire quality, length & thickness depend how many time heat spread and resist with that heat. K.watt/ Watt = Applied voltage x Ampere. Many quality and types of electric heating elements are there depend upon purpose of use. Few best heating elements known as Kanthal wire, Nicrome wire, Ureka wire, Super Kanthal, Silicon Carbide heating elements etc.

What costs more in electricity - electric heater or electric guitars?
electric heater
What does high or low voltage do to the capacity of an electric heater?
Yes, voltage effects the output of electric heaters. The wattage output rating of the heater will not be reached due to the lower applied voltage. For example if the heater is 5000 watts at 277 volts, the current is I = W/E 5000/277 = 18 amps. The resistance of the heater is R = W/I (squared) = 5000/18 x 18 (324) = 15.43 ohms. Applying 220 volts on the same heater whose resistance is 15.43 ohms results in this new heater wattage rating. W = E (squared)/R = 220 x 220 (48400)/15.43 = 3137 watts. W = watts, I = amperage, R = resistance in ohms and E = voltage.
Is the hot water heater gas and electric?
Gas heater & electric heater both are available.
What is the true power when using a V supply voltage and a kW heating element with a voltage rating of V?
True power is expressed in watts, so the true power of your heater is its kilowatt rating at its rated voltage. Variations in voltage will result in variations in its power. Assuming its resistance remains roughly constant for variations in temperature, then True Power = V2/R.
