An electric kettle draws a current of 10 A when connected to the 230 V mains supply. if all the energy produced in 5 minutes is used to heat 2 kg of water (Specific heat capacity of water = 4200 J kg-1 K-1.), determine the following: a. the power supplied to the kettle, in kW b. the electrical energy consumed c. the rise in temperature of the kettle. (Please show proper units in the solution)
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.
