Typically resistance rises with temperature.
What else can I help you with?
Does the resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
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.
What current will flow through the heating coil when the heater is plugged in?
The current flowing through the heating coil will depend on the resistance of the coil and the voltage of the power source. Using Ohm's Law (I = V/R), where I is the current, V is the voltage, and R is the resistance, you can calculate the current. The higher the voltage or lower the resistance, the higher the current.
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.
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.
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.
What is the current through the 150 ohm heater?
At 110 volts it is 0.8 amps. At 220 it is 0.4 amps. I=E/R. I=amps.E=volts R=resistance.
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.
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 is the voltage across an electric water heater element that has a resistance of 32 ohms when the current through it is 6.8A?
It is 6 times 8 and the answer is in volts.
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.
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
