Characteristics of resistor in series and parallel connection?

Answer 1

Resistors in series add resistance to an electrical circuit. For instance two 1 ohm resistors in series will have 2 ohms of resistance.

Resistors in parallel divide the resistance between them. Thus two 2 ohm resistors in parallel will have 1 ohms total resistance.

resistors of different sizes work the same way. a 4 ohm and 2 ohm resistor in series have 6 ohms resistance. While in parallel they will have .75 ohm resistance.

resistance formulas:

series: Req = r1+r2+r3....+rx

parallel: Req = 1/r1 + 1/r2 + 1/r3 ..... +1/rx

Answer 2

You can not connect two resistors in both parallel and series configuration, it is either one or the other.

Resistors connected in parallel have the same voltage (symbol: V), measured in volts, "across" them, which means that the voltage at their terminals is the same.

Resistors connected in series have the same current (symbol: I), measured in amps, running through them.

A resistor is characterized by its resistance (symbol: R), measured in ohms.

The equation: R = V/I , (Ohm's law) describes the relation between resistance, voltage and current.

From this definition, the following results follow:

Two resistors in series:

negative ---R1---R2--- positive

Where R1 and R2 are the resistors "---" are copper cables or the terminals of the resistors, "positive" and "negative" represent the positive and negative terminal of a battery.

The resistance of two resistors "R1" and "R2" in series is: R = R1 + R2

Two resistors in parallel:

|---R1---|

negative ---| |--- positive

|---R2---|

The resistance of two resistors "R1" and "R2" in parallel is: R = (R1*R2)/(R1+R2)

In practice, resistors connected in parallel are always equivalent to a "smaller" resistor, and resistors in series are always equivalent to a "bigger" resistor.

Answer 3

Quite badly, i taught one just last year, he kept punching his classmates

Answer 4

Resistors can be connected in series or in parallel

with other resistors or with other components.
