In the given figure, the current through the 20 V battery is:
Answer & explanation
Correct answer: option 1
Potential difference across 4Ω resistance (20 + 16)V current through 4Ω resistance
= 36V = $\frac{36}{4}$ = 9A [From top to bottom]
Similarly, current through 2Ω resistance = $\frac{20-46}{2}$ = 2A
