Question

could someone please help me with this question. .​

Answer 1

Since two resistor are in series of 5 and 20ohm so

Rs = 5+20 = l25ohm

Again 2 are in series of 15 and 10ohm

So

Rs = 10 + 15 = 25ohm

Now both Rs is in Parallel

so

1/Req = 1/25 + 1/25

Req = 25/2 ohm

Req = 12.5

we know that from ohms law

v = iReq

i = v/Req

i = 24*2/25= 48/25A

i = 1 .92A
