What Is Alternating Current And Voltage?


An alternating voltage is any voltage that varies in both magnitude and polarity with respect to time. The voltage may vary in a regular, predictable manner, or the voltage may vary in an irregular, nonrepetitive manner with respect to time. In either case, the voltage is considered to be an alternating voltage.

What is alternating current circuit?

Alternating Current Circuits or AC circuits are simply circuits powered by an Alternating Source, either current or voltage. An Alternating Voltage or Current is one in which the amount of either the voltage or the current alters about a distinct mean value and reverses direction periodically.


What is an alternating current class 12?

Alternating current is defined as the current that varies like a sine function with time. The value of current will oscillate between a maximum value and a minimum value. In case of AC the current is changing its magnitude at every instant of time.


What is AC and DC current class 12?

In alternating current, current keeps switching directions periodically – forward and backward.

In AC the flow of current changes its direction backwards periodically.It flows in a single direction steadily.


Is gold representative money?

Representative money is an item such as a token or piece of paper that has no intrinsic value but can be exchanged on demand for a commodity that does have intrinsic value, such as gold, silver, copper, and even tobacco. An item has intrinsic value if it still has value even if it is not used as money.

Can you give at least 5 example of sports involving projectile motion?

A projectile is anybody which is thrown or jumped into the air. Once it has left the ground it will follow a flight path called a parabola until it once more comes back down to earth. This applies to balls, javelins, discus, long jumpers, high jumpers, and horses showjumping.


How do changes in matter affect our life?

Example, matter will change in shape, size, state and appearance. We can cut the paper into different shapes but it is still paper. In chemical change, the matter will be converted from one state to another state. Example, the wood changes into smoke and ash then it will produce heat and light.

How do I calculate my interest rate online?

The principal amount is Rs 10,000, the rate of interest is 10% and the number of years is six. You can calculate the simple interest as: A = 10,000 (1+0.1*6) = Rs 16,000. Interest = A – P = 16000 – 10000 = Rs 6,000.
