# series and parallel resistor circuits

series and parallel resistor circuit and how to calculate its value. resistors are the most common components we encounter in electronics. Resistor serves to inhibit the flow of electricity

In the Resistor there is a code that states the resistance value of a Resistor. The code is found on the color bracelets attached to the Resistor body

To calculate series and parallel resistor circuit will admin explain in the following article

In general, the resistor value has been determined by the manufacturer with a certain value. But sometimes we need resistors with certain values ​​that are not available in the market

If you experienced it or you is doing a trial using a resistor then you can string up some resistors into series and parallel resistor circuit to obtain a certain value

The value of resistor circulating in the market

There are also Resistor values ​​have been determined by the factory is as follows

• 1
• 1.2
• 1.5
• 1.8
• 2.2
• 2.7
• 3.3
• 3.9
• 4.7
• 5.6
• 6.8
• 8.2

apply every multiplier of 10

The unit resistance value of the resistor is ohms. The other values ​​are 1K = 1000R and 1M = 1000K

To obtain a resistor with a certain value we can combine the resistor in series or parallel

## series resistor circuit

The total value of the Series Resistor is the sum of all Resistor values

Here’s more details Example we need a resistor with a value of 2 k while we know that the resistors we meet in the market does not exist with a value of 2 k so we need to combine the resistor so that it becomes series resistor series as in the picture above

### Series Resistor Formula

In series resistor series then apply the following formula

Rt = R1 + R2

So from the description of the image above the total resistor value is 1 + 1 = 2 k

## parallel resistor circuit

Resistors can also we arrange in parallel

Example as in the picture of a series of parallel resistors

### Parallel resistor formula

The formula for a series of parallel resistors is

1 / Rt = 1 / R1 + 1 / R2

The total value of resistors in the circuit is resolved is 500R

Benefits of making series and parallel resistor circuits

With our string resistor as resolved, surely it can save the cost than we have to use a variable resistor and can have a resistor with a value that is not available in the market
