Question

plz solve this ..............​

Answer 1

Answer:

R in series= 25+75= 100 ohm

R in series= 10+x ohms

total R in parallel= 20 ohm

according to question...

=> 1/20= 1/100+1/x+10

=>1/20= 10+x+100/1000+100x

=>1000+100x= 2200+20x

=> 80x= 1200

*****=>x=150 ohm *****

V=IR

I= 6/20

I= 0.3 A
