Kashif Bashir4 The applied voltage V A is the same across parallel branches

Kashif Bashir5 The applied voltage V A is the same across parallel branches

Kashif Bashir6 Each branch I equals V A /R

Kashif Bashir7 The main line I T equal the sum of the branch current

Kashif Bashir8 Resistance in parallel

Kashif Bashir9 Why R eq is less then any branch R

Kashif Bashir10 Reciprocal Resistance Formula We can derive this formula from the fact that I T is the sum os all the branch currents or. I T = I 1 + I 2 + I 3 + …… etc

Kashif Bashir11 Reciprocal Resistance Formula

Kashif Bashir12 Conductance in parallel G is equal to 1/R. G T = G 1 + G 2 + G 3 + …….. etc
