Home inverter is to provide uninterrupted power to run household electric devices. These are available in different voltage and load capacities. In the basic design of the inverter a DC (battery) source is connected to a transformer through the center tap of the primary winding. A switch is rapidly switched back and forth to allow current to flow back to the battery following two alternate paths through one end of the primary winding and then the other. The alternation of the direction of current in the primary winding of the transformer produces alternating current (AC) in the secondary circuit. This will be 230 /110 Volt AC and can operate all the electric devices.
In Disc capacitors, only a number is printed on its body so it is very difficult to determine its value in PF, KPF, uF, n etc. In some capacitor, its value is printed in uF eg.0.1 in some others EIA code is used e.g. 104. Here explains the method to identify the Disc capacitor Article in Word Format Capacitors Continue reading Disc Capacitor.How to identify?
As you know the resistor is an inevitable part of a circuit. It is meant for reducing the current and voltage in the circuit parts. Resistors are identified using the standard colour code chart. A simple trick can be used to identify the resistor value range. The third colour band on the body of the resistor represents the multiplier value. So by identifying the third … Continue reading Tips to Identify Resistors
The easiest way to connect computer peripherals is through a Universal Serial Bus. The USB is a plug-and-play interface between the PC and the peripherals. The advantage of USB is that the device can be plugged in or plugged out without the need of restarting the PC. Here explains the working of USB. USB is the short form of Universal Serial Bus, a standard port … Continue reading USB. How it works?
Static electricity is an imbalance in the amount of positive and negative charges found within the surface of an object. The sudden flow of static electricity or Electrostatic discharge (ESD) can interfere with the operation of electronic circuits especially the circuits using CMOS and Microprocessor devices.
