Since power is current times voltage, doubling current while keeping voltage the same will double the power. Ignoring slight non-linearity, if the power doubles, the heat will double.
The electric heater is basically a resistor, designed to have the right resistance to draw the required current. So a 2 kW heater designed for a 230 v supply is really a resistor of 28.8 ohms, so when it's connected the current is 8 amps and the power is 2 kW.
Power is VI so 360 watts.
A DC power supply supplies directional current in an electric motor. This is significant because many motors run on directional current, or DC power; it's easier to convert to kinetic energy than alternating current (AC), which is generally used to transmit power over long distances.
The electric heater draws some of the electrical current in the circuit, which reduces the current available for the electric bulb. This leads to a decrease in the brightness of the bulb as it is receiving less power.
The heater element is a coiled wire resistor that draws enough current to supply the intended amount of power, which might be 1.5 - 3 kW. Quickly the temperature of the wire rises until it reaches an equlibrium where the heat power conducted away by convection is the same as that draw from the power supply.
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
Yes, an electric heater will use less kWh on a lower setting since less power is being consumed to generate heat. Lower settings require less energy to maintain the desired temperature, resulting in lower energy consumption overall.
The power rating of the electric space heater is 3480 watts (29 A * 120 V).
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.
11.5 x 240 = 2760W motor.
Wires supplying electric current to a water heater need to carry more current due to the higher power requirement of the water heater. Thicker wires are used to reduce resistance and prevent overheating when carrying this increased current. On the other hand, wires supplying current to lights carry a lower power load, so thinner wires can be used effectively.
Power = Volts * current [p = E*I]; 120volts*10amps = 1200watts
Power = (current) x (voltage)2,000 = 8 VV = 2,000/8 = 250 volts if the power factor is ' 1 ' and everything is operating as marked
Electric rating of 1Kw
OK. First, note that your heater doesn't 'generate' power. If it did, you could sell the power. Your heater consumes power. The electric company generates it, and you pay them for it. The power consumed on a household circuit is nominally (Voltage) multiplied by (Current). The voltage delivered to your house is nominally 117 volts AC, although it can vary by a bit. If the current through the heater is exactly 5 Amp, then the power is (117 x 5) = 585 watts, or 0.585 KW.
