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.
Does resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
What will happen if you pass dc current through a single coil?
If dc current is passed through a single coil, it is going to remain constant.
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 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.
Working principle of ammeter?
An ammeter consists of a coil with very low resistance. when electric current flows through the coil, the coil induces a magnetic field which turns the needle.
What is the highest and lowest voltage of an electromagnet?
The strength of an electromagnetic is determined completely by the current through its coil, and doesn't depend on the voltage across the coil. The voltage will be (current) x (resistance of the coil).
What would happen if the current passing through the coil was too large?
The coil offers some amount of Resistance to the flow of Electric current through the coil. The Resistance of the coil depends on the material used to make the coil and the thickness of the coil wire ( its gauge ) When a current flows through the coil, the voltage drop across the coil and the Power dissipated in the coil both are proportional to the magnitude of current and the coil resistance. Normally the coil is rated to carry certain current and dissipate certain amount of power without causing any damage. If a large magnitude of current flows through the coil beyond its rating , the voltage drop across the coil and the power dissipation in the coil both increase substantially causing over heating of the coil. This can damage the coil and may result in burning of the coil
Why does the core of a transformer heat up?
The resistance to the electric flow through the wire coil causes heat
Which of the coil of the wattmeter has high resistance?
The voltage (or 'potential') coil has the higher resistance, because it is connected in parallel with the load.
How does a copper coil heats water?
A copper coil heats water when electricity passes through it, generating heat in the coil due to its electrical resistance. This heat is transferred to the surrounding water, raising its temperature.
