Problem

In a series circuit, three resistors

R_1

,

R_2

and

R_3

are connected to an ideal battery of emf

V

. Which of the following gives the potential difference

V_2

across

R_2

? (a)

V_2 = \dfrac{R_1+R_2}{R_1+R_2+R_3}\,V

(b)

V_2 = \dfrac{R_1+R_2+R_3}{R_2}\,V

(c)

V_2 = \dfrac{R_2}{R_1+R_2+R_3}\,V

(d)

V_2 = \dfrac{R_2}{R_1+R_3}\,V
