In the Philippines, the standard voltage in homes is 220 V instead of the 120 V used in the United States. Therefore, a “100-W” Philippine bulb would be intended for use with a 220-V potential difference. (a) If you bring a “100-W” Philippine bulb to the United States, what should be its U.S. power rating? (b) How much current will the 100-W Philippine bulb draw in normal use in the United States?
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.
