Question

If the three resistances R1, R2 and R3 are connected in parallel , Then find its relation .

Class Tenth.​

Answer 1

r1, r2 and r3 are in parallel connection

Therefore the equivalent resistance :

1/req= 1/r1 + 1/r2 +1/r3

1/req= (r2r3 + r1r3 + r1r2) /r1r2r3

req= r1r2r3/r2r3 + r1r3 + r1r2

Hope it helps :)
