The calculator does not go to 3 spots after the decimal and therefore, shows 0.00 0.01 / 3 = 0.00333--> 0.01 (resistor value) / 3 (number of resistors) = [parallel resistance value] With multiple resistors of the same value this is all you need to do to know the parallel resistance: Know the value of the resistor (R) Know how many resistors you are using (N) read the output (x) Here is the . For example, you can use two resistors of 3Ω, 6Ω, respectively. Two resistors in parallel: I 1 = I T R 2 / (R 1 + R 2) More than two resistors in parallel: To solve for I 1, find the combined resistance of all resistors besides R 1. In the circuit of Figure 1, first use the parallel resistance formula to find the equivalent resistance R123. where V1 - V2 is the potential difference, E is the field strength in Newton / Coulomb, r is the distance in meters between points 1 and 2, the same as the potential, in the International System of Units the potential difference is measures in volts. Equivalent resistance may sound complicated, but it's just a technical way to say . V 1 = V 2 = V 3 = V. Current flowing through each resistor is inversely proportional to its resistances . The multiple branch lines in a circuit mean there are several pathways for the charge to move to the external circuit. Conductance is symbolized with the letter "G" and is measured in units of mhos or Siemens. Make any parallel circuits equal to one resistor. For circuits with more than two parallel resistors, simply work out two . Then the series resistance formula tells us RTOT = R123 + R4. For resistors in parallel the equivalent circuit resistance R T is calculated differently.. An electrical circuit is a path or line through which an electrical current flows.
