An automotive battery has an emf of 12.0 V. When supplying power to the starter motor, the current in the battery is 16 A and the terminal voltage of the battery is 11.2 V. What is the internal resistance of the battery?
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.
