Question

please answer this class 10 electricity
pleaseee​

Answer 1

2 series combination are in parallel

Resistance of one combination is 1 series combination is

R=r+r

=10+10

=20ohm

One parallel combination therefore,

1/R=(1/r) * 2

(As both resistances are the same 20 ohm)

1/R=(1/20)*2

=1/10

R= 10 ohm

Potential difference = 3v

I = V/R

I = 3/10

I = 0.3 A

The current drawn from the battery is 0.3 amperes
