Find the expression for the equivalent resistance of 3 resistors (R1,R2.R3) connected in parallel. Sol. In a parallel connection, voltage drops across the resistors so: Using, Ohm's Law we derive, that 1 = V1/ 12 = V2/ I3=V3/ Since, the voltage is the same on all resistors, then V= V1 - Substituting to the, first equation above, we get the following |- V/ + V2/ + V3 So: 1 1 1 1 + R2 Reg R1 R3
