Astitva: after giving the answer

Astitva: In 12 ques the 1 ohm and 3 ohm resistor are in series therefore it will be 4 ohm. The 1+3 and 4 ohm resistor are parallel therefore resulting resistance is ½ ohm. Now ½ and 15 are in series. therefore R is equal to 17 ohm. By formula, V=IR, 17= I*17, I=1A.
