Question
If three resistors R1, R2 and R3 are connected in series and by R1 > R2 > R3, then what is the relation between the currents I1, I2 and I3 respectively flowing through them?
Options
I1 = I2 = I3
I1 < I2 < I3
I1 > I2 > I3
`1/I_1 < 1/I_2 < 1/I_3`

Solution
I1 = I2 = I3
Explanation:
In a series circuit, current has only one path, so the same current flows through every resistor. Thus (I1 = I2 = I3), independent of the resistance values.
