A 12-ohm resistor is connected to a 30-volt battery with an internal resistance r. While connected to the battery, the 12-ohm resistor dissipates energy at a rate of 48 joules per second. Determine the value of the internal resistance r.
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.
