Question

Four resistors each of 50ohm are connected in parallel. Find equivalent
resistance.

Answer 1

Answer:

Explanation:

when the resistors are in parallel, take the inverse and add. after getting the solution, take its inverse again.This will be the required answer

In this case:

1/R= 1/50 + 1/50 + 1/50 + 1/50

1/R= 0.02+0.02+0.02+0.02

1/R= 0.08

R= 1/0.08

R= 12.5 ohm

Answer 2

Answer:

Parallel Resistence ={ 1÷Rp}=(1÷R1) +1÷R2)+... so on until you add the reciprocal of all resistors.

Explanation:

Here ,

1/Rp ={(1/R1) +(1/R2) +(1/R3) +(1/R4)}

        =1/50 +1/50 +1/50 +1/50

         = 4/50

∴1/Rp = 4/50

∴Rp =50/4

       =12.5Ω
