A light bulb is connected to a 240-V wall socket. The current in the bulb depends on the time t according to the relation I = (2.828 A) sin[(628.0 Hz)t]. (a) What is the frequency of the alternating current?Hz(b) Determine the resistance of the bulb's filament?Ω(c) What is the average power delivered to the light bulb
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.
