+### what is current?
+Current is the flow of electric charge, measured in amperes. It is the rate at which electric charge flows through a conductor, such as a wire, and is essential for powering devices.
+Current னு சொல்றது wire ல electron-ங்க move ஆகுற flow தான், அதாவது electric charge conductor ல பாய்றது. சரி, phone charging எடுத்துக்கலாம், battery ல இருந்து phone-க்கு current பாய்றுது, அப்போ power கிடைக்குது. அதனால, current இல்லனா phone charge ஆகாது, ஏன்னா electron flow இல்ல. உதாரணமா, நம்ம வீட்ல wire-ல current பாய்றுது, அதனால தான் light, fan எல்லாம் வேலை செய்யுது. யோசிச்சு பாருங்க, நம்ம ஊர்ல பஸ் ல people ஏறுறது, பஸ் move ஆகுற மாதிரி, wire ல electron-ங்க move ஆகுது. இவ்ளோதான், clear ஆ இருக்கா?
