7812 Based 12 Volt DC Power Supply Circuit
Many electronic projects need 12V clean power for output devices like LCD, graphic LCD and DC motors. A simple AC to DC converter using 7812 regulator. It provides fixed 12V for small devices and general use. Big 100uF capacitor remove big AC ripple from rectified DC. Small 0.1uF capacitor remove small ripple from regulated output. […]
Voltage Vs Current Explained Simply
Electricity works because of voltage and current. Both are basic parts of any electric circuit. Voltage gives energy. Current shows how much charge is flowing. They are related but not the same. Let us understand both in simple words. What is Voltage? Voltage is the electric force or pressure. It pushes electrons to move in […]
