Current electricity is the most common form of electricity that is used to power up devices and appliances. Learn the generation of current electricity and more.
and the graph of ac looks like a sine wave, which means the current flows to and fro, our household current changes directions 50 times a second; hence you can see 50hz written on most of our electrical equipment. the below videos help to revise the chapter electricity class 10 frequently...
Electric current is the rate of change of electric charge through a circuit. This electric current is related to the voltage and resistance of the circuit. Using Ohm’s law, we can represent as the formula: I=VR Where, Since we measure the charge in coulombs and time in seconds, therefor...

costs that result from a one-unit change in the production rate. We find marginal cost by subtracting the total cost of producing all but the last unit from the total cost of producing all units, including the last one. Marginal costs can be measured, therefore, by using the formula: ...
Thus, de-carbonization should not only include the electricity generation sector, but the industry sector as well. However, nuclear power suffers from a controversial image, and typically addressed negatively in the public eye. The two main factors being, the safe operation of the plants and the...
