Question

Three resistances with value 10, 4, 2 ohm respectively are connected in parallel combination. The total resistance ​

Answer 1

Answer:

17/20

Explanation:

let...R1= 10 ohm

R2= 4 ohm

R3= 2 ohm

therefore.....total resistance

R= 1/R1 + 1/ R2 + 1/ R3

= 1/10 + 1/4 + 1/2

= (2+5+10)/20

= 17/20
