Question

what is the equivalent resistance across A and B?​

Answer 1

Answer:

1/12+1/6=3/12

4 ohm

hope you have understand follow me for further help

Answer 2

Answer:  IN THIS QUESTION,SAME CURRENT FLOWS THROUGH 3 ohm,4 ohm AND 5 ohm

SO,THEY ARE IN SERIES

SO,R=12

6 OHM IS PARALLEL TO THESE 3 RESISTORS,

SO,

1/R=1/12+1/6

1/R=1+2/12

R=12/3

R=4  OHM

HOPE MY ANS IS CLEAR!!THK U!!
