Question

plz solve it soon it's important

Answer 1

I can't solve 1st one here because it can be solved only by kirchoff law. which will be lenthy so im going to solve 2nd one.(And i dont understand which side of battery is +ve)

So In 2nd one

3 and 3 are in seris so =6 ohm is parallel to another 6 ohm=3 ohm is series with another 3 ohms =6 ohm is parallel with another 6 ohm =3 ohm is series with 3 ohm and 3ohm =9 ohm ans.

Answer 2

For 1st ques

1st step- add 30 and 30 in parallel    30*30/30+30=15

2nd step-then add 15 ,15 and 15 in series    15+15+15=45

so, R = 45 ohm

now for current = voltage/ resistance

voltage given 3V

I = 3/45 =1/15

For 2nd ques

1st step- add 3 and 3 in series     3+3=6

then 6 and 6 in parallel    6*6/6+6=3

2nd step- add 3 and 3 in series     3+3=6

then 6 and 6 in parallel    6*6/6+6=3                            

3rd step- add 3 ,3 and 3 in series     3+3+3=9

so, R=9

for current in this ques there is not given voltage

hope it helps

if ans is wrong then inform

and if ans is correct then mark as brainliest
