INTRODUCTION: This is a standard circuit which can be used to adjust the brightness of mains lights and the speed of AC motors. It uses a triac‚ diac and has a radio-frequency interference (RFI) noise suppression circuit built into it as well. The circuit controls the average power to a load through the triac by phase control. The AC supply is applied to the load for only a controlled fraction of each cycle. The triac is held in an OFF condition for a portion of its cycle then is triggered ON at

Introduction In our daily life‚ we use lots of electrical objects‚ such as‚ air cooler‚ electric fans‚ etc. In those objects‚ if there is leakage current‚ means‚ if a short circuit is made there‚ then the leakage current may cause a lot of harm to us. If unknowingly

place the peaks at the reference level. A diode clamp (a simple‚ common type) consists of a diode‚ which conducts electric current in only one direction and prevents the signal exceeding the reference value; and a capacitor which provides a DC offset from the stored charge. The capacitor forms a time constant with the resistor load which determines the range of frequencies over which the clamper will be effective. In electronics‚ a clipper is a device designed to prevent the output of a circuit

of the voltage divider biasing circuit for CE amplifier. It sets up proper operating point for the BJT. Input Capacitor C1 It couples the signal (small AC signal‚ vs) to the base of the transistor. It blocks any DC component present in the signal and passes only ac signal for amplification. Because of this biasing conditions are maintained constant.
