Advantages and Disadvantages of A.C and D.C
What comes to your mind first when you hear about AC and DC currents ? No! Don’t open your textbooks, yet! For many students learning secondary physics, AC and DC generally means - Alternating Current Direct Current However, we all know that this knowledge is not enough to write in exams or solve problems related to the same. You need to understand how alternating current (AC) and direct current (DC) work. Let us give you an example. When you plug your phone into the charger and switch on the current, what current do you think runs through the circuit? Well, it's the AC that's emitted from the plug and enters the charger. But it’s the charger that changes that transforms that current into DC. This is because alternating current keeps changing directions. And you can’t afford to use that current inside your phone. There is a small circuit inside every charger that converts AC from the wall into DC before sending it into your ph...
