At the top 10 ohm and 10 ohm resistors make 20 ohm Then 20 ohm and 10 ohm are in series , therefore 30 ohm Now 30 ohm resistor and 10 ohm resistor are parallel , therefore 1/ Req = 1/30 + 1/10 Req = 7 5 ohm 3 I = V/R V = 3V R = 7 5 ohm 4 I = (3/7 5) A = 0 4 A (Ans)

At the top 10 ohm and 10 ohm resistors make 20 ohm.
Then 20 ohm and 10 ohm are in series , therefore 30 ohm

Now 30 ohm resistor and 10 ohm resistor are parallel , therefore 1/ R_eq = 1/30 + 1/10 ... R_{eq =} 7.5 ohm
3. I = V/R V = 3V R = 7.5 ohm
4. I = (3/7.5) A = 0.4 A (Ans)
