What is a resistor made of?

The resistive element is made from a mixture of finely powdered carbon and an insulating material, usually ceramic. A resin holds the mixture together. The resistance is determined by the ratio of the fill material (the powdered ceramic) to the carbon.

What is the major difference between a resistor and inductor?

The main difference between ideal resistors and ideal inductors is therefore that resistors dissipate electrical power as heat, while inductors turn electrical power into a magnetic field. Ideal resistors have zero reactance and as a result zero inductance.

What is difference between coil and wire?

is that wire is (label) metal formed into a thin, even thread, now usually by being drawn through a hole in a steel die while coil is something wound in the form of a helix or spiral or coil can be a noise, tumult, bustle, or turmoil.

What is a resistor coil?

A Ballast Resistor is an electrical device that reduces voltage to the coil so that more energy is available for the spark plugs during starting.

What is the difference between inductor and conductor?

One of the fundamental contrasts between a conductor and an inductor is that a conductor goes against an adjustment of voltage while an inductor goes against an adjustment of the current. Besides, the inductor stores energy as an attractive field, and the conductor stores energy as an electric field.

What is the similarity between inductor & resistor?

Both inductor and the resistor are linear devices. The current drawn by the inductor and resistor varies in the same proportion as the voltage is varied. The phase shift in current and voltage in case of resistive circuit is zero. The power factor of the resistive circuit is unity.

What is a coil in physics?

coil, in an electric circuit, one or more turns, usually roughly circular or cylindrical, of current-carrying wire designed to produce a magnetic field or to provide electrical resistance or inductance; in the latter case, a coil is also called a choke coil (see also inductance).

How do you connect a coil to a resistor?

Strip the end of the positive wire from the ignition, and connect it to the positive end of the resistor. From the other terminal on the resistor a wire goes to the positive on the coil. Make sure to attach securely to the connecting terminal, by wrapping the wire around the post and tightening with a screwdriver.
