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 does a heater do in a circuit?
A heater in a circuit converts electrical energy into thermal energy through resistive heating. When current flows through the heater's resistive element, it generates heat due to the resistance encountered by the electric current. This heat can be used for various applications, such as warming a space or heating fluids. Essentially, the heater increases the temperature of its surroundings by dissipating energy in the form of heat.
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.
What is resistance heater?
A resistance heater is a type of heating device that generates heat through the process of electrical resistance. When an electric current passes through a resistive material, it encounters resistance, which converts electrical energy into thermal energy. These heaters are commonly used in various applications, including industrial processes, space heating, and household appliances like toasters and electric stoves. They are known for their efficiency and simplicity in design.
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.
