power adapter for a laptop computer is rated at P = 73 W (meaning this is the highest power it can handle before the circuits start to fail). The voltage of the battery is represented as ΔV. (a) If the laptop is used at a potential difference of 12 V what is the maximum current it can draw in terms of P? (b) What is the minimum internal resistance of the laptop in Ω? (c) How much energy in joules does the laptop consume in one hour at maximum?
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.
