An electric light bulb rated at 100 W is left on for 10 days and nights. (a) How much energy was expended? (b) How long must an electric heater rated 3500 W be left on to expend the same amount of energy?
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.
