Best Answer

The resistance of the coil does not remain the same throughout the experiment because the voltage across and the current is varied.

Typically resistance rises with temperature.

Typically resistance rises with temperature.


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 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.


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 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


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).


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.


When Replacing 12v coil on 1998 Kubota engine wg750 could it have resistance type external wiring from coil to distributor or is resistance internal in coil?

A engine coil has a high internal resistance, the needing of a suplementar resistance may be advised to you by a car electrician, who works with such brand and model of your car.

Light bulbs how does running electricity through the bulb create light?

The electricity runs through a coil of Tungsten. Tungsten has a very high resistance. As per Joule's Law, energy radiated is directly proportional to resistance. The energy radiated is so large that the coil starts to glow and light is produced.
