Answer 1

Answer:

Voltage across 10 ohm resistance is 20 v means current through thorough this resistance is 2 amp.

And two 20 ohm resistance are to each other parallel and in series with 10 ohm so net resistance will be 20 ohm and terminal voltage is 40 volt then also for upper both terminals.

so for 15 ohm resistance

40 = 15 × I

$then \: current \: throgh \: 15 \: ohm \: resistance \\ i \: = \frac{40}{15}$

hope the answer will help you
