The different sets of standard resistor values are known by their e series numbers.

Resistors in series pdf. The two main characteristics of a resistor are its resistance r in ohms and its power rating p in watts. Resistors circuits module 2pdf 1 e. To calculate the total resistance for these three resistors in series 100 w 82 w 1 w 183 w task 1.

In many electrical circuits resistors are connected in series or parallel. In the next picture we again see three resistors and a battery. The wattage rating indicates the amount of power the resistor can safely dissipate as heat.

The most basic series within the e range is the e3 series which has just three values. Series parallel circuits now that we have our circuit resistance of rt we can calculate circuit current by using ohms law. E3 has three resistors in each decade e6 has six e12 has twelve and so forth.

Have the same voltage drop across them seriescurrentparallelvoltage. A designer might for example combine several resistors with standard values e series to reach a specific resistance value. There are three distinct paths that current can take before returning to the battery and the associated resistors are said to be in parallel.

Resistors in series when resistors are connected one after each other this is called connecting in series. This is gives the following formula. To calculate the total overall resistance of a number of resistors connected in this way you add up the individual resistances.

Rtotal r1 2 r3 and so on example. From there we can mix and match. King from the manchester.

The resistance r provides the required reduction in current or the desired drop in voltage. This resistive value of 8w is now in parallel with r2 from which we can calculated rd as. There is only one path for the current to follow.

If rt 73w and e 100v i 100 73 1369 amps or 137 a the parallel resistors must be reduced to a single series value before being added to the series resistor. Rc is in series with r3 therefore the total resistance will be rc r3 8w as shown. This is shown below.

1 22 and 47. It seems reasonable that the total resistance is the sum of the individual resistances considering that the current has to pass through each resistor in sequence. Rd is in series with r1 therefore the total resistance will be rd r1 4 6 10w as shown.

Many types of resistors are used having different uses and construction.

Resistor construction resistors are components used to resist the flow of electric current and have a stated value of resistance.
