Question

.1 what is the equivalent resistance of whole circuit
.2what is the main current ​

Answer 1

Answer:

The voltage drop is the same across each parallel branch. The sum of the current in each individual branch is equal to the current outside the branches. The equivalent or overall resistance of the collection of resistors is given by the equation 1/Req = 1/R1 + 1/R2 + 1/R3 ...
