Two bulbs (each with resistance 2Ω) are to be connected to an ideal source of emf (ℰ=8V) and negligible internal resistance. Find the current through each bulb and the potential difference across each bulb if the bulbs are connected in (a) series (b) in parallel. (c) Suppose one of the bulb bums out and cur.ent can no longer flow through it, what happens to the other bulb in the series case? in the parallel case?(Note: Draw the resistor network)
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.
