+ (a) (b) (c) Assume that the batteries and the light bulbs in the circuits are identical. Choose all the the correct statements below: Currents passing the bulbs are different with Ia < Ib lb > lc. ) The battery wired in circuit (a) lasts the longest. | The batteries wired in circuit (c) last the longest.
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.
Observe the given the three circiut diagrams.in this three circuits identical voltage sources .It's mean in case voltage sources are in series we can add each other for getting total voltage value.but here the voltage sources are parallel (in parallel voltages are same) so no difference in voltages .Given above three diagrams have equal voltages. And also bulbs also identical in three diagrams.so same current is flowing in three circuits (Ia=Ib=Ic).
