With 3 different resistors connected in parallel, when connected to a battery source with electromotive force V, the power drawn by the circuit is measured as 120 W. The resistance of the second lamp is twice the resistance of the first lamp. The resistance of the third lamp is three times the resistance of the second lamp. If these 3 lamps are connected in series, what is the total power supplied by the circuit?
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.
