On three separate instances you connect each lightbulb to a battery with an emf of 12.00 V and an internal resistance of 0.5 Ω. When a current of 4 A passes through the battery, what is the resistance in the LED, CFL (compact fluorescent light) and incandescent lightbulbs?
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.
