Series connection

Series connection of 2 resistors
Specifications in ohms

Voltage
Resistor 1
Resistor 2
T. resistance
T. conductance
Amperage
This calculator calculates the compensating resistance, respectively the total conductance for two resistances connected in a series, and the results are given in ohms.

If an applied voltage is specified, the resulting total current is also given.


Series connection of 2 resistors
Specifications in Siemens (conductance)

Voltage
Conductance 1
Conductance 2
T. conductance
T. resistance
Amperage
This calculator uses the compensating resistance (as resistance und electric conductance) for two resistances connected in a series, and the entry is made in Siemens (electric conductance).

If an applied voltage is specified, the resulting total current is also given.





Series connection

Series connection of max. 9 resistors
Specifications in ohms

Resistor 1
Resistor 2
Resistor 3
Resistor 4
Resistor 5
Resistor 6
Resistor 7
Resistor 8
Resistor 9
T. resistance
T. conductance
This calculator gives the compensating resistance, respectively the total conductance for up to nine resistances connected in a series. The resistance (ohms) is expected as entry.

0 in the entry field means no resistance (resistance-free connection).


Series connection of max. 9 resistors
Specifications in Siemens (conductance)

Conductance 1
Conductance 2
Conductance 3
Conductance 4
Conductance 5
Conductance 6
Conductance 7
Conductance 8
Conductance 9
T. conductance
T. resistance
This calculator uses the compensating resistance, respectively the total conductance for up to nine resistances connected in a series, specifying the electrical conductance.

An empty entry field means no resistance (resistance-free connection).

For the connection of a series of resistances the sum of all the partial voltages equals the total voltage. The current strength is the same for all the components. The total resistance is equivalent to the sum of the individual resistances.

Calculation basis for the above resistance calculator:
The formula it is based on is capacity RTotal = R1 + R2 + ...
The 2nd decimal point is rounded up, and for the conductance the 4th decimal point is rounded up.






Electric conductivity, conductance

Resistance
Conductivity
This calculator converts the resistance into the conductance.

The electrical conductivity is the reciprocal value of the electrical resistance. Its formula sign is G, its measuring unit is S (Siemens). Some calculations can be more elegantly achieved with conductance as the quantity for the resistance.

The calculation basis for this conductivity converter:
The formula this is based on is R=1/G.
The 5th decimal point in the result is rounded up.






Error messages

Overflow appears when the value to be displayed is too large for the display field. The other displayed values remain valid.

NaN (Not a Number) appears when an invalid number was entered in one of the input fields, most commonly an entry containing an incorrect decimal character (e.g. point and not comma), a letter or a thousands separator.
