An Inverter is a small circuit that converts the direct current (DC) to alternating current (AC). The power of a battery is converted into main voltages or AC voltage. We can use AC power for electronic appliances like television, mobile phones, computer etc. The basic function of an inverter is to convert DC to … Read more
Traffic Lights Controller are used to control the vehicular traffic on the road. In the modern age, almost everyone has different types of vehicles that become the cause of traffic problems. That is why traffic lights signals are compulsory to avoid the traffic jams on the roads. There are three signals lights in the traffic … Read more
BC548 is a commonly used NPN transistor, the same as BC547. The collector and emitter will remain open when the base pin is held at ground and will close when a signal is provided to the base pin. BC548 has a gain value of 110 to 800; this value determines the amplification capacity of the transistor. … Read more
Sometimes due to power failure, our home appliances burnt or our work stoped badly. To overcome this problem we have to use alternate power to continue our work without any hesitation. We use UPS batteries or generators as alternate power supply. If we change our power manually its a big problem for us. The main … Read more
