Light bulbs of the same material and properties are connected in parallel to a battery. Each of the bulbs has a resistance of 15 Ω, while the battery has an internal resistance of 0.50 Ω. The emf of the battery is twice the terminal voltage of the battery. How many bulbs are connected?
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.
