Question

answer this pls with steps!!! ​

Answer 1

In the given circuit

2 resistors of 20 ohm and 15 ohm are connected in series

the resultant resistance of the combination is

Rs =15+20

Rs = 35 ohms

the resultant combination is connected to a battery of 7V

the current flowing through the combination is

I = V /R

I = 7/35

I =1/5

I=0.2 A

We know that , in series combination the current flowing through the Resistors is the same but potential Difference varies

V(20)=I ×20

V(20)=0.2×20=4V
