Question

Resistor (R1) = 2 and (R2) =5 then Resistance in parallel combination =?
Explain properly also​

Answer 1

Answer:

Resistance in parallel combination = 1/2 +1/5 =5+2/ 10 = 7 /10 = 0.7 ohm

Answer 2

Answer:

10/7

Explanation:

When resistors are connected in parallel combination then the following formula is used for adding them

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

So we have R1=2ohm R2=5ohm then,

1/R =1/R1+1/R2

     =1/2+1/5 = 7/10

1/R = 7/10

R= 10/7

I hope this answer helped you:)
