Your Lecturer in class made the following statement: "We do not buy electrons from Eskom but we buy electrical energy!". Electrical Poerr can be described as electrical energy unit time. Electrical Energy can be brought from ESKOM in units of R2,50 for 1 KiloWatt- hour. How much will it cost to operate a 1200 W hairdryer continuously for 30 minutes? A. R3,00 B. R1,50 C. 60c D. R6,00
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.
