In a series circuit containing three resistors

R_1, R_2

and

R_3

, the currents

I_1, I_2

and

I_3

through them respectively are (a)

I_1 R_1 = I_2 R_2 = I_3 R_3

(b)

I_1 : I_2 : I_3 = \dfrac{1}{R_1} : \dfrac{1}{R_2} : \dfrac{1}{R_3}

(c)

I_1 = I_2 = I_3

(d)

I \propto R

for each resistor (currents increase with resistance)
