Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.

For an AC circuit we often deal with the peak voltage and RMS voltage. The maximum positive value of the voltage of an AC source is the peak voltage and the RMS voltage of an AC source is the square root of the mean of the square of the voltage of the AC source.
Given that,
The RMS voltage of the source
The current through the bulb,
