A circuit provides a maximum current of 20.0 A at an operating voltage of 1.20x102 V. (a) How many 75 W bulbs can operate with this voltage source? (b) At $0.120 per kilowatt-hour, how much does it cost to operate these bulbs for 8.00 hr?
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.
