If a motor with a large inertial load decelerates quickly it will act as an alternator and send voltage back to the drive which then sends it back to the power supply. Because many regulated power supplies feature protection circuitry this may cause the power supply to fault or reset; however, if the supply is unregulated it will simply get absorbed by the filter capacitor.

The circuits and components of a double-layer PCB board are usually connected in one of two ways: either utilizing a through-hole or with the use of a surface-mount. A through-hole connection means that small wires, known as leads, are fed through the holes, with each end of the leads then soldered to the right component.

When the diode is reverse biased (the anode connected to a negative voltage and the cathode to a positive voltage), as shown in Fig. 2.0.6, positive holes are attracted towards the negative voltage on the anode and away from the junction. Likewise the negative electrons are attracted away from the junction towards the positive voltage applied to the cathode. This action leaves a greater area at the junction without any charge carriers (either positive holes or negative electrons) as the depletion layer widens. Because the junction area is now depleted of charge carriers it acts as an insulator, and as higher voltages are applied in reverse polarity, the depletion layer becomes wider still as more charge carriers away from the junction. The diode will not conduct with a reverse voltage (a reverse bias) applied, apart from a very small ‘Reverse Leakage Current’ (IR), which in silicon diodes is typically less than 25nA. However if the applied voltage reaches a value called the ‘Reverse Breakdown Voltage’ (VRRM) current in the reverse direction increases dramatically to a point where, if the current is not limited in some way, the diode will be destroyed.
By Alix Loane. Circuit. Published at Thursday, October 26th 2017, 18:28:29 PM. Resistors, capacitors, and inductors are the fundamental components of electronic circuits. In fact, all electronic circuits can be equivalently represented by circuits of these three components together with voltage and current sources.
By Sasha Sara. Circuit. Published at Wednesday, October 25th 2017, 18:12:08 PM. An electric current is defined as free flow of electrons and the motivating force behind that free flow of electrons is called Voltage. Voltage is the measurement of potential energy that would move the electrons between two points. Voltage is the push that the electrons require to move within a circuit. Voltage is measured by Volt and Current is measured by Ampere.
By Sasha Sara. Diagram. Published at Tuesday, October 24th 2017, 18:09:15 PM. As discussed earlier, a digital circuit represents and manipulates information encoded as electric signals that can assume one of two voltages – logic-high voltage (or Vdd) and logic-low voltage (or GND). A digital circuit requires a power supply that can produce these two voltages, and these same supply voltages are also used to encode information in the form of two-state, or binary signals. Thus,if a given circuit node is at Vdd, then that signal is said to carry a logic ‘1’; if the node is at GND, then the node carries a logic ‘0’. The components in digital circuits are simple on/off switches that can pass logic ‘1’ and logic ‘0’ signals from one circuit node to another. Most typically, these switches are arranged to combine input signals to produce an output signal according to basic logic relationships. For example, one well-known logic circuit is an AND gate that combines two input signals to produce an output that is the logic AND of the inputs (i.e., if both input1 and input2 are a ‘1’, then the output is a ‘1’).
