Question

Please help me with this question fasstttt .

Answer 1

Explanation:

Here 1 ohm, 5 ohm and 10 ohm are in parallel ( i.e R4, R3 and R2 are in parallel ) . They have same potential dfference .

So, 1/10 + 1/1 +1/5

= ( 1 + 10 + 2 ) / 10

= 13 / 10

= 1.3 ohm

now 1.3 ohm series combination with R1

1.3 + 1 = 2.3 ohm
