Question

three resistors 3ohm,4ohm,12ohm are connected in parallel. What is the effective resistance of the combination​

Answer 1

Answer:

parallel resistance=R1 +R2+R3

=> parallel resistance= 3+4+12

=> parallel resistance= 19 ohm

Answer 2

Answer:

1.5

Explanation:

1/Req=1/R1+1/R2+1/R3

1/Req=1/3+1/4+1/12

1/Req =4/12+3/12+1/12

1/Req =8/12

Req=12/8

= 1.5

Remember the formula Of parallel combination
