Best resources .An Operational Amplifier, or op-amp for short, is fundamentally a voltage amplifying device designed to be used with external feedback components such as resistors and capacitors between its output and input terminals.
Starting out you need to cover basic electronics which encompasses the topics of ohms law, voltage, current, resistance, capacitance, inductance, reactance, impedance and Q. .Basic Electronics Tutorials - Electronics Post. Introduction To Electronics. Electronics and Its Importance. Electronic Components. Resistors. Resistor Color Codes. Resistors . Magnetic Hysteresis Loop. The Magnetic Hysteresis loop above, shows the behaviour of a ferromagnetic core graphically as the relationship between B and H is non-linear. Starting with an .Active Low Pass Filter. Active filters such as an active low pass filter, are filter circuits that use an operational amplifier (op-amp) as the their main amplifying device along with some resistors and capacitors to provide a .DC Motors. DC Motors are electromechanical devices which use the interaction of magnetic fields and conductors to convert the electrical energy into rotary mechanical energy. Electrical DC Motors are .An autotransformer is used mainly for the adjustments of line voltages to either change its value or to keep it constant. If the voltage adjustment is by a small amount, either up or down, then the transformer ratio is small as VP and VS are nearly equal. Currents IP and IS are also nearly equal. Therefore, the portion of the winding which .Electromagnetic Induction was first discovered way back in the 1830’s by Michael Faraday. Faraday noticed that when he moved a permanent magnet in and out of a coil or a single loop of wire it induced an E lectro M otive F orce or emf, in other words a Voltage, and therefore a current was produced. So what Michael Faraday discovered was a way .
The above circuit uses two first-order filters connected or cascaded together to form a second-order or two-pole high pass network. Then a first-order filter stage can be converted into a second-order type by simply using an additional RC network, the same as for the 2 nd-order low pass filter.The resulting second-order high pass filter circuit will have a .
Capacitor Tutorial Summary. A capacitor consists of two metal plates separated by a dielectric. As we will see in this capacitor tutorial, Capacitors are energy storage devices which have the ability to store an electrical charge across its plates. Thus capacitors store energy as a result of their ability to store charge and an ideal capacitor .
Transistor switches can be used to switch and control lamps, relays or even motors. When using the bipolar transistor as a switch they must be either “fully-OFF” or “fully-ON”. Transistors that are fully “ON” are said to be in their Saturation region. Transistors that are fully “OFF” are said to be in their Cut-off region.Op-amp Comparator. The comparator is an electronic decision making circuit that makes use of an operational amplifiers very high gain in its open-loop state, that is, there is no feedback resistor. The Op-amp comparator compares one analogue voltage level with another analogue voltage level, or some preset reference voltage, V REF and produces .
Resistor tutorial summary listing the main points we have learnt through this tutorial section about resistors and resistance. The job of a Resistor is to limit the current flowing through an electrical circuit. Resistance is measured in Ohm’s and is given the symbol Ω. Carbon, Film and Wirewound are all types of resistors.The Capacitance of a Capacitor. Capacitance is the electrical property of a capacitor and is the measure of a capacitors ability to store an electrical charge onto its two plates with the unit of capacitance being the Farad .
1. Uni-directional Waveforms – these electrical waveforms are always positive or negative in nature flowing in one forward direction only as they do not cross the zero axis point. Common uni-directional .An NTC thermistors reduces its resistance with an increase in temperature and are available in a variety of base resistances and temperature curves. NTC thermistors are usually characterised by their base resistance at .electronics tutorials ws electronics hubMagnetism. Electromagnetism is the force produced when an electrical current flows through a simple conductor such as a piece of wire or cable. While magnets can be made from ferromagnetic materials which attract (and repel) other materials, mainly metals. Magnetism is the force exerted by magnets as they attract or repel each other.
A Hartley Oscillator circuit having two individual inductors of 0.5mH each, are designed to resonate in parallel with a variable capacitor that can be adjusted between 100pF and 500pF. Determine the upper and lower frequencies of oscillation and also the Hartley oscillators bandwidth. From above we can calculate the frequency of oscillations .
The logic AND Function. The Logic AND Function function states that two or more events must occur together and at the same time for an output action to occur. The order in which these actions occur is unimportant as it does not affect the final result. For example, A & B = B & A. In Boolean algebra the Logic AND Function follows the Commutative .
Inductance of a Coil. Inductance is the name given to the property of a component that opposes the change of current flowing through it and even a straight piece of wire will have some inductance. The inductance of a coil refers to the electrical property the inductive coil has to oppose any change in the current flowing through it.The circuit on the left shows a single resistor-capacitor network whose output voltage “leads” the input voltage by some angle less than 90 o.In a pure or ideal single-pole RC network. it would produce a maximum phase shift of exactly 90 o, and because 180 o of phase shift is required for oscillation, at least two single-poles networks must be used .
