What is the difference between inductance and resistance?

In: Physics

Resistance is inductance over time.

You measure inductance in Henry and Resistance in Ohm and an Ohm is a henry divided by a second.

The relationship between the two concepts is not too different from the difference between the questions of “how far?” and “how fast?”.

Resistance is the opposition to the flow of current (marbels being forced down a rubber tube with a ‘tighter’ section in it)

Inductance is the opposition to the change in flow of current (stops the marbles from changing their speed drastically)

Inductance is basically the strength of a magnetic field. Inductance has its own kind of “resistance” called reactance.

inductive reactance exists in ac circuits and since it is alternating it is the opposition of rising and falling magnetic fields. It is determined by the voltage applied and directly proportional to frequency.

Resistance is basically molecular friction and is determined by the material which is carrying the voltage, more specifically the number of electrons on the valence ring of the atom.

Using these two values, resistance and reactance gives you a final value called impedance.

resistance resists current, inductance resists *change* in current.

you can think of a circuit with high inductance like a shopping cart that’s heavy. it’s hard to get moving, and it’s hard to stop, but once it starts moving it will keep going with little effort.

Voltage is how many more (or less) charge carriers A has compared to B

Current is how quickly the charge carriers move from A to B

Resistance restricts electrical curent.

Inductance resists a change In current. It does this by storing energy in a magnetic field in a process known as energizing. Faraday’s Law describes this process

Capacitance resists a change in voltage. It does this by storing energy in an electric filed in a process known as charging. This occurs when you have two opposite charge carriers in close proximity but no viable path to each other eg. Two metal plates separated by a tiny insulation layer
