Circuit Diagram Resistance Calculator. Resistance of a circuit is defined as the ratio of the voltage applied to the electric current which flows through it. In a circuit connected in series the total resistance is found by simply adding up all the resistance values of the individual resistors whereas in parallel it is found by adding up the reciprocals of the resistance values and taking the reciprocal of the total.
If you don t know the individual values use the ohm s law equation where resistance voltage divided by current. Just enter 2 known values and the calculator will solve for the others. Know the value of the resistor r know how many resistors you are using n read the output x here is the.
Calculate the total series and parallel resistance of a circuit using digikey s parallel and series resistor calculator.
Just add the number of resistors in the first column and then enter the values of each resistor with selecting the proper unit of resistor value in ω kω or mω. Calculate the total parallel resistance. Build and simulate circuits right in your browser. Design circuits online in your browser or using the desktop application.
