# Does it matter which way you use a resistor?

Does it matter which way you use a resistor? No the resistors are bidirectional and can therefore be used in both directions. Do not go wrong with the colored lines, it’s just to say the approximate resistance. The resistors are purely passive components and have a linear response when the voltage is applied to one or the other polarity.

Which way do you install a resistor?

Does it matter if resistors backwards? Electrically, no difference either way.

Is there a positive and negative side to a resistor? Resistors don’t care which leg is connected to positive or negative. The + means where the positive or red probe of the volt meter is to be placed in order to get a positive reading.

## Does it matter which way you use a resistor? – Additional Questions

### How do you determine the polarity of a resistor?

The polarity of the voltage drop across any resistive component is determined by the direction of current flow through it: positive entering, and negative exiting.

### Which way does current flow through a resistor?

To solve circuits using KCL and KVL, the current arrow across a resistor goes from the + voltage to the – voltage. Conversely, the current arrow across a battery goes from the – voltage to the + voltage. This is the same thing as saying current comes out of the battery’s + terminal and into the battery’s – terminal.

### Does the resistor go on the anode or cathode?

Since this resistor is only being used to limit current through the circuit, it can actually be located on either side of the LED. Placing the resistor on the positive (anode) side of the resistor will have no differing effects from placing the resistor on the negative (cathode) side of the LED.

### How do you find the polarity of a voltage?

The magnitude of a voltage can be either positive or negative. If the voltage magnitude is positive, the voltage has the same polarity as shown on the diagram. If the voltage magnitude is negative, the voltage polarity is the opposite to that shown on the diagram.

### What does a 470 ohm resistor look like?

470 Ohm Resistor Color Code

The four band 470 resistor is easy to recognize with its’ distinctive pattern of yellow, violet, and brown color bands. The 5 and 6 band versions have a pattern of yellow, violet, black, black, followed by the tolerance band and temperature coefficient band on the 6 band version.

### What does R stand for in resistor?

Resistance (R) is a property of a material used for describing the opposition provided to the flow of current. The higher the resistance provided by a material, the lower the flow of electrons or current through the material.

### What color is a 2K resistor?

2K Ohm Resistor Color Code: Red, Black, Red, Golden. Resistance: 2K Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 11.18mA .

### What color code is 4.7 ohms?

4.7 Ohm Resistor Color Code: Yellow, Violet, Golden, Golden. Resistance: 4.7 Ohm, Power Rating: 0.25 Watt, Approximate Maximum Current: 231mA .

### How can you tell if a resistor is 100 Ohm?

How can you tell if a resistor is 100 ohm? The color code for the four bands 100 Ohm resistor is brown, black, brown, gold. 4-band 100 ohm resistor color code is calculated as: 1st-band= Brown= 1 (1st digit) 2nd-band= Black= 0 (2nd digit).
