Question

please answer this question.

Answer 1

1...The current in series arrangement is equal at all points
hence, the current in resistor of 5 ohm is 2A
by applying ohm's law
hence, current flowing through resistor R is also 2A
2...V=IR
so, R=V/I
hence, R= 15V/2A
so, R= 7.5 ohm
.....hope it helps
