The two hown below are four simple electric circ ent shaped bulbs are different types, but all circular bulbs are identical, as are all oval bulbs. Assume the oval bulbs have a higher resistance than the circular bulbs. Circuit 1 A Circuit 2 II Circuit 4 Circuit 3 IV
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.
Let the resiistance of the circular bulb be Rc and the oval bulb be Ro ,and Ro>Rc(Given)
Case 1st
I1=V/Rc
Case 2nd
I2=V/Ro
Case 3rd
Equivalent Resistance=Rc+Ro
So,
I3=V/(Rc+Ro)
Case 4th
Eqivalent parallel resistance
