Paper capacitors are among one of the basic types of capacitors. Generally, in a capacitor the conducting material is separated by the dielectric. Based on the variant that is utilized as dielectric different types of capacitors are formed. The construction of this capacitor is similar to that of other capacitors, for example, plastic capacitors. The only difference between the other capacitors and this capacitor is that the dielectric chosen is of paper type. What is a Paper Capacitor? A … [Read more...]
Capacitor Introduction, Working & Applications
Capacitors are the basic element of any circuit that requires the smoothening of signals. These elements are widely preferred for the blocking of the DC signals. Whenever a capacitor is supplied with the DC voltage the positive charge is settled at one side of the plate. The remaining negative charges are shifted at another plate. In this way, the charges have attained a state of stability. Hence the positive and the negative charges neutrally arranged on the plates. This is the reason when … [Read more...]
Film Capacitor, Introduction, Working, Types, and Uses
Film Capacitor is one of the most popular and widely used capacitors. These possess a difference in their properties of dielectric. In the modern type of film capacitor, there is the ‘direct electrical connection' establishment with the electrodes that are present on both the winding's. This keeps the path of the current to the electrode very short. This capacitor has various benefits like it has very low ESR(ohmic resistance) and ESL(Parasitic Inductance). This can be preferred in various AC ap … [Read more...]
Variable Capacitor Construction, Working Types and Uses
Variable Capacitor is one of the type of basic capacitors. Based on the capacitance, capacitors are classified under two categories. These are referred to as ‘Fixed Capacitors' and the ‘Variable Capacitors'. The capacitors with the capacitance value are fixed are known as ‘Fixed Capacitors'. Similarly, the capacitors that are with varying amounts of capacitance are known as Variable Capacitors. This type of capacitor has the capability of changing the values of its capacitance either "Elec … [Read more...]
Capacitor Basics and its Different Types Along with its Symbols
Capacitor Basics Capacitor are the basic electronic components of any analog or digital circuit and it is known for its charge storing capabilities. There are different Capacitor types available. Capacitor is made up of two conducting metal plates separated by a non-conducting dielectric material like paper,ceramic etc. When ever a supply is applied to the capacitor the electrons start moving from one plate to the other and it starts accumulating on the other plate as the dielectric in … [Read more...]
Capacitor Polarity, Identification of Polarities for Various Types
Capacitor Polarity is an important point to be considered during the connections. There are various capacitors, some of them are ‘polarized' and some are classified under the category of ‘non-polarized'. Both types possess ‘two terminals’. The difference between these two types of capacitors is very simple. If the capacitors considered are polarized then the terminals classified are referred to as ‘Anode' and ‘Cathode'. These must be connected based on the supply's polarity. If the capacitors co … [Read more...]
Non-Inverting Amplifier Circuit Diagram, Gain & Applications
Non-Inverting Amplifier Theory The non-inverting amplifier is the basic circuit obtained from amplifiers. As it name goes the circuit helps in achieving the non-inverted output at the final stage. Although the inverting amplifier is preferred in many cases it has two drawbacks. Firstly, the output obtained at the final stage of it is an inverted one. Obtaining an inverted output further requires any other setup to be connected to further invert the inverted output. The second drawback which is … [Read more...]
Push-Pull Amplifiers Circuit Diagram, Working and Applications
Push-pull amplifiers are the combinations of two bipolar junction transistors that is one of P-N-P type and the other is of N-P-N type. In this combination one act as push type and the other acts as pull type. If the single-stage amplifiers are utilized lot of heat dissipation occurs in the circuit and so the efficiency is less though it gives 90% amplification of the input signal. But where the higher values of efficiency are concerned then these amplifiers with two stages are utilized. One … [Read more...]
Power Amplifier Circuit Diagram, Types and Applications
Basics of Power Amplifier Power amplifier are the basic category of amplifiers which is used to amplify the power of the input signal which may be either a digital signal or an analog signal from few milli watts to several milli watts depending on the need of amplification. These types of amplifiers are found in almost every analog to digital devices sorrounding us. From radio tuners to microwave to laptops to cell phones use power amplifiers in some form or the other. What is a Power … [Read more...]
Audio Amplifier Circuit, Working, and Applications
Audio amplifier is the basic circuit configuration that is required to amplify, the audio signal received through a device like a microphone or the audio signal that is to be transmitted out through a speaker/ Radio device/Wireless transmitter etc. In early stages, in the year around 1912 vaccum tubes where used for audio amplification but at around 1970s it was replaced by BJT and MOSFETS. ClassD power amplifiers (which uses transistors/MOSFETS) are the most widely in audio amplification. C … [Read more...]
