Question

Two resistance one of 20 ohm and other of 30 ohm are connected in parallel and this combination is connected in series with 8 ohm resistance and 12 volt battery. The current in 30 ohm resistance is?

Answer 1

frist calculate total resistance that is
$\frac{1}{20} + \frac{1}{30 } = \frac{1}{12}$
so its is 12 ohm and then in series so
12 plus 8
equals 20
plz give me some heaerts
then equivalent resistance is 20 ohm
put formula v=ir
v= 12
r= 20
okk

Answer 2

first calculate total resistance that is

1/20 +1/30 = 1/12

so its is 12 ohm and then in series so

12 + 8 = 20ohm

then equivalent resistance is 20 ohm

so by applying ohms law means its formulea  that is V= IR

V= 12

R= 20

so , 12 = 20 x I

    12/20 = I

   0.6 A = I

hope you understand . please mark as brainliest answer.
