what is general formula of resistance. 2 A certain resistor in a circuit has a resistance of 3000 kO. As an example if three resistors having values of 1 kohm 2 kohm and 3 kohm are placed in series then the total resistance is 1 2 3 kohm 6 kohm.
Its formula is given as. Rearrange V IR to solve for resistance. 3 O 20 O 32 O.
The most common and widely accepted PREn formula is.
R 400 O. Plug the values you found into this formula to solve for total resistance. Its formula is given as. In general if we have n resistors.
