Question

find the total resistance in parallel if a resistance of 10 ohm and 20 ohm are connected in parallel

Answer 1

Answer:

1/R=1/10+1/20

1/R=.2+1 /20

1/R=3/20

R=20/3

Explanation:

hope it is correct

please follow me

Answer 2

Answer:

20/3 or 6.66 ohms

Explanation:

effective resistance when connected in parallel =1/R1+1/R2

here R1=10 ohm R2 =20 ohm

1/Reff=1/10+1/20

=2/20+1/20

=3/20

Reff=20/3

Reff=6.66ohms

Hope it helps.
