In the circuit below, when the switch (“S”) is open the Voltmeter (“V”) reads 3.08 V. When the switch is closed the Voltmeter reading drops to 2.97 V. and the Ammeter (“A”) reads 1.65 A. (a)What is the EMF (“E”), Internal resistance (“r”) of the battery? (b) What is the circuit resistance (“R”)? Assume that the two meters are ideal. (c) What is the potential difference 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.
