A 60W lightbulb in your house is left on for 21 minutes while you do some of your Foundations of Physics homework. A quick google tells you that the mains voltage in Australia is 230V. How many electrons pass through the lightbulb in that time?
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.
