Inductor That Looks Like A Resistor

October 28, 2019

If you look at the equation for calculating the impedance above you will notice that it looks like the equation for calculating the hypotenuse of a right triangle. The voltages across the resistor v r and the inductor v l are shown in the diagram at the right angle to each other.

I have to do some troubleshooting and repairs and noticed this component.

Inductor that looks like a resistor. I have taken alot of what apeared to be resistors out of things. Just as with the rc circuit the inductor voltages approach to 0 volts and the currents approach to 15 amps over time is asymptoticfor all practical purposes though we can say that the inductor voltage will eventually reach 0 volts and that the current will eventually equal the maximum of 15 amps. Is there any way to tell other than by using an ohm meter wether its an inductor or resistor.

Most things i beleve to be inductors are gree with coding stripes like resistors however have seen green used on. Physics ninja looks at an ac circuit problem with an inductor and a resistor. Measure the dc resistance with a multimeter if its that much different than its code then its an inductor for sure.

It will thus look like a resistor and inductor properties do not apply. If under a few ohm then its probly an inductor. Dipped axial lead inductors tend to have a specific kind of lumpy look because of the wire whereas resistors are fairly regular in their midsection.

Inductor and resistor in. Their sum is always greater than the total voltage v t. It looks like a resistor has colored stripes like a resistor but has a green body as opposed to the traditional beige of neighboring resistors and is in spot marked for a capacitor.

An inductor looks like a piece of wire to dc. If it says something like r37 on the other hand its probably a resistor. Beyond that resistors sometimes have a specific body color as ignacio says but not always.

Attached is a photo from the motherboard in my commodore 64. You can make sure its an inductor by measuring its impedance at different frequencies an inductors impedance will increase with the frequency whilst a resistors imedance wont. Physics ninja looks at an ac circuit problem with an inductor and a resistor.

Then somwhere i figured out some inductors look like resistors too.
