Resistors Which Way Round

For instance i have one which is either. Nope no wrong way.

If the tolerance band is red the resistance will be within 2 of 27k or within 1 if brown is used.

Resistors which way round. Ive just bought a bag of random resistors from maplin and cant work out which way round the six band ones should be read. Just temporarily whilst they bounce round in the resistor for in there are less paths for free electrons. Most resistors have four stripes of color.

However does it matter which way the resistor is facing on a wire such as 4th line comes first before the other lines. If the circuit contains resistors then these will slow the electrons down. It is however a good idea to put them all the same way with the tolerance band in the same direction if youre gonna ever need to debug the circuit.

Some resistors have five stripes of color with four representing the resistance value and the last one the tolerance. So you can put it in anyway. Does it matter which way the resistor is facing in a wire.

If you have a hundred on a circuit board it makes sense. Liz 1 decade ago. Also the tolerance band on the end will be silver or gold which is not in the normal sequence so you can tell its the tolerance band the first digit is on the opposite end.

Violet orange red brown brown red. In a wire the positive if i am correct is where you put the resistor. The first three stripes indicate the resistance value and the fourth stripe indicates the tolerance.

If its in doubt measure. Red brown brown red orange violet. A gold tolerance band is possibly the most common you will find on standard carbon film resistors.

The distance between the case of a resistor and the bending point should be at least five millimetersresistors are placed on the circuit board either horizontally or vertically but in no way. The red band at either the right or left appears thicker than the others. Resistors arent polarity wise.

Usually first band will be closest to the end. Unless you manage to get hold of some very old resistors silver which represents 10 tolerance will rarely if ever be seen as the tolerance band. Resistors have no polarity so they work fine in either direction but you want your circuit to be readable so it is good practice to pick a direction and go with it that way you can just read your stripes without having to flip the thing around in hand or in head.

If theres only 2 or 3 it doesnt matter.
