A water heater that is connected across the terminals of a 15.0 V power supply is able to heat 250 ml of water from room temperature of 25°C to boiling point in 45.0 secs. What is the resistance of the heater? The density of water is 1,000 kg/m2 and the specific heat capacity of water is 4,200 J/kg/°C
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.
