What else can I help you with?
How much current will an electric heater draw from a 110-volt line if the resistance of the heater when hot is 26.7 ohm?
4.12A. V=IR
What is stepped resistor?
The resistance that controls a heater motor in the electric system .
If a 325 watt heater has a current of 6.0A what is the resistance?
Watts = Current x Volts with your resistive heat application. To figure out resistance you need to know voltage and current. Since you are drawing 6 amps then Volts = 325/6. This means that there is about 54 volts supplying the heater which seems like a very strange supply voltage. Since Volts = Current x Resistance the resistance = 325/36.
What current is taken by a heater with a resistance of 24 ohms when connected to 120 volt supply?
I don’t know
If the current through a heater coil is 5 amp and the supply voltage is 120 volts the coil resistance is?
The formula you are looking for is R = E/I. Resistance = Volts/Amps.
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.
Mr Heater F274800 Portable "Big Buddy" Heater is a electric heater?
Mr Heater F274800 Portable "Big Buddy" Heater is a propane gas heater.
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 much current will an electric heater draw from a 110-volt line if the resistance of the heater when hot is 26.7 ohm?
4.12A. V=IR
Does an electric motor have different resistance than an electric heater?
Yes it would be unlikely an electric motor coincidentally exactly matched the resistance of an electric heater.
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.
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.
Examples of heating effect of electric current?
-kettle -electric heater that's all i have! :)) When a current passes through a wire, the wire heats up. This is caused by the conversion of electrical energy into heat energy. /the heat produced depends on the resistance of the wire.
What energy transfers are used in the electric coil of a basebord heater?
The energy transfers in the electric coil of a baseboard heater involve electrical energy being converted to thermal energy through the resistance of the coil. When current flows through the coil, the resistance generates heat, which warms the surrounding air in the room.
When a single phase supply connect to a electric heater short circuit not there why?
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.
What is stepped resistor?
The resistance that controls a heater motor in the electric system .
How does an electric heater coil work to generate heat in a heating system?
An electric heater coil works by passing an electric current through a resistive material, usually made of metal. The resistance in the material causes it to heat up, generating heat that warms the surrounding air in the heating system.
