The cost of operating an electric heater in a hospital is 2.61 dollars daily. The heater has a resistance of 8 ohm drawing 12 A current from service main. How many hours is the heater operated if the cost of one kilowatt per hour in Florida is 11.37 cents (11.37 cents per kWh).
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.
