A hospital electric heater of the resistance 10 Ω draws 18 A current from the service main. At what rate is the thermal energy developed in watts (W)? What is the cost of operating the heater for 24 hours if the cost of one kilowatt per hour in Florida is 11.37 cents (11.37¢ / 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.
