Question

the current in the given circuit

Answer 1

Answer:

4) 3.2 A

Explanation:

1. 6 ohm parallel to 6ohm, equalant resistance is 3 ohm
2. 3 ohm and 3 ohm ( step 1 resultant) parallel, equalant resistance is 1.5 ohm.
3. V/R = 4.8/1.5 = 3.2 A

Answer 2

Answer:

The answer is 2A.

Explanation:

We can open R2 and R3 from their corresponding ends. Then we would observe that they are in series and parallel to R1.

Then,

Rs=R2+R3

=6ohm+6ohm=12ohm.

Rp=1/Rs+1/R1=1/12+1/3=1+4/12=5/12=2.4.

Given,V=4.8v

According to Ohm's law,

V=IR

=>V/Rp=I=>4.8v/2.4ohm=2A.
