If you want to compute the total resistance of less than 10 resistors just insert the values of the resistors you have and leave the rest of tbe fields blank. This is done using the following formula.Įnter resistances into the boxes below and when all values have been input click on the calculate button and the result will appear in the box below that button. This calculator allows up to 10 different resistor values.
This is shown below.įor example a can paint a room in 5 hours and b can paint a room in 6 hours. Parallel resistors can also be interchanged with each other without changing the total resistance or the total circuit current. To use it just specify how many parallel resistors there are and the resistance value for each one. R eq 11r 11r 21r 31r n here is an example given r 1 20 w r 2 30 w and r 3 30 w. Parallel resistance is when the in side of 2 or more resistors are connected and the out side of those resistors are connected. When resistors are connected one after each other this is called connecting in series. The equation is 1rtotal 1r1 1r2 1r3 1rlast. The equation for combining n resistors in parallel is. This calculator determines the resistance of up to 10 resistors in parallel.Īdd resistors in parallel calculator.
