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

∙ 12y agoYou 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.

What are the characteristics of series connections?
Characteristics of parallel connection.
In a simple circuit is a battery in series or parallel with the resistor?
In series.
How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
How do you connect resistor?
In a circuit, either in Parallel or in Series with other components.
What is a resistor bank?
In simple way resistor bank contains number of resistors in series or parallel combination. They are connected in parallel to decrease the resistance and increase current rating and power dissipation.And they are connected in series to increase resistance and power dissipation.
What are the characteristics of series connections?
Characteristics of parallel connection.
What are the laws of series and parallel connection?
1.In series connection the total resistance is equal the total number of resistor that was connected in series 2.the current is constant in a series connection 3.in a series connection total voltage is equal the number of of volt per cells
In a simple circuit is a battery in series or parallel with the resistor?
In series.
How is series clipper differ from parallel clipper?
Series clipper diodes are in series connection with the load while Parallel clippers are in parallel connection with the load.
What is the constant electrical quantity in a series connection and a series-parallel connection?
constant electrical quantity-series connection -current constant electrical quantity-parallel connection - voltage
What is the difference of a series connection and a parallel connection?
A series connection will not work if one bulb fuses but in a parallel connection if one bulb fuses the rest will stay lit.
Where does a fuse has more chances of tripping when connected with a series connection or parallel connection?
series connection
What is the total resistance of a 5-ohm resistor and a 10-ohm resistor in a parallel series?

How should voltmeter be connected to measure the potential difference across a resistor - in series or in parallel?
In parallel.
How do you connect resistor?
In a circuit, either in Parallel or in Series with other components.
What will happen to the other resistor if the number of resistor decreases?
the voltage across that resistor will increase if it is in series with the other resistors. the current through that resistor will increase if it is in parallel with the other resistors.
What is series - parallel connection?
In series connection current will be same. in parrel connection voltage will be same and current wil be varying
