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.
A certain toaster has a heating element made of Nichrome
wire. When the toaster is first connected to a 110-V source (and the
wire is at a temperature of 20.0°C), the initial current is 1.67 A. The
current decreases as the heating element warms up. When the toaster
reaches its final operating temperature, the current is 1.51 A.

The operating voltage of the toaster V=110V
The current flowing through the toaster at the operating temperature I=1.51A
The power delivered to the toaster P=VI
P=110*1.51
P=166.1W
