Have you ever thought about toll plazas on the highway which scan vehicles fast tags very quickly and accurately? Fastags it uses RFID tags which stands for radio frequency identification. RFID is used in many places such As for tracking inventory or collection of tolls on the highway. Let’s quickly understand this in … Read more
The energy density of Lithium-ion batteries is higher, which means it can store large amounts of power in even small sizes. These batteries use electrolytes, that is why the batteries are not flexible and come only in 2 shapes that are rectangular and cylindrical. A Lithium-ion batteries can charge 300-500 times only. After these recharge … Read more
First we have to understand AC (alternating current) and DC (Direct current). The main difference between alternating current and direct current is in the direction they flow. Direct current flows constantly in a single direction and alternating current flows back and forth constantly changing its flowing direction and magnitude. Because of this nature the alternating … Read more
