V1 = V2 R1 AB I R2 V Equivalent circuit B A I Re q V
AB I R2 V In parallel connection reciprocal of equivalent resistance is sum of reciprocals of individual resistances. .
For 2 resistances R1 I R2 V
For n resistances in parallel, R1 R2 R3 I Rn V
In parallel connection, Reciprocal of Equivalent resistance is the sum of reciprocal of individual resistances.
For n resistances in parallel, R1 R2 R3 I Rn V If, R1 = R2 = R3 =...... = Rn = R
In parallel combination, resistors/ devices are connected one after the other Current gets distributed. Voltage remains constant. Reciprocal of Equivalent resistance: Sum of reciprocals of individual resistances.
