It would be P=VI, so 29A*120V=3480Watts

Why are wires supplying electric current to the water heater thicker than those supplying current to the lights?
the water heater operates at high power compared to the lights and so the water heater requires a larger current. The wires supplying current to the water heater are thicker so that the wires have a low resistance. This reduces the risk of the wires overheating.
What is least expensive to run a heater with 750 watts and 7.1 amps or 600 watts and 12.5 amps?
The heater with 750 watts and 7.1 amps is less expensive to run. This is because it has a lower amperage, meaning it requires less electric current to operate. The 600-watt heater with 12.5 amps requires a higher electric current, which could translate to higher electricity costs.
Does an electric heater use less kwh on lower setting?
Yes. It draws less current.
Introduction of heating effect of electric current and electric heater fuse metals used for thermocouple?
Can heat energy be converted to light energy and how?
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.

Why does the cord of an electric heater not glow while the heating element does?
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
Why voltage is low while using heater as home appliance?
The current is proportionately high as heater requires current to heat the filament.The voltage is deliberately low to sustain the safe power consumption limits.
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.
Is electric heater require oxygen to burn?
No, electric heaters work by running electric current through resistors which produces heat. same as an element on an oven range top.
