An intuitive way to understand the behavior of voltage and current in electronic circuits is to use hydrodynamic systems as an analogue. In this system, voltage is represented by gravitational potential or height of the fluid column, and current is represented by the fluid flow rate.

A rise in die temperature (regardless of cause) approaching the limit threshold (about 160°C) will cause the thermal shutdown to cut drive to the power transistor, thereby reducing load current and internal power dissipation. Note that the thermal limiter can override both the current limit circuits and the voltage error amplifier. Thermal shutdown is detailed in the next section.

The slide switches are also known as “single throw-double pole” (STDP) switches, because only one switch (or throw) exists, but two positions (or poles) are available (a pole is an electrical contact to which the switch can make contact). These switches can be set to output either Vdd (when the actuator is closest to the board’s edge) or GND. The push button switches are also known as “momentary” contact buttons, because they only make contact while they are actively being pressed – they output a GND at rest, and a Vdd only when they are being pressed. The figure below shows typically pushbutton and slide switch circuits used on Digilent boards.

By Madeleine Catherine. Diagram. Published at Tuesday, December 26th 2017, 06:12:51 AM. Several different resistors are used on Digilent boards. Some are used to limit LED current, and some are used on inputs (like the button and switch circuits) to both limit the currents flowing to the main chip, and to help protect against electrostatic discharge (or ESD – more on this topic later). The resistors on the Digilent boards, like most resistors used in digital systems, are physically small because they will not encounter large voltages or currents. For these smaller resistors, the resistor value in Ohms is printed in microscopic numbers on the resistor body, not visible to the naked eye.

The unloaded PCB appears green because thin sheets of green plastic have been applied to both sides (otherwise the PCB would appear pale yellow). Called solder masks, these sheets cover all exposed metal other than the component pads and holes so that errant solder can not inadvertently short (or electrically connect) the printed wires. All metal surfaces other than the exposed pads and holes (i.e., the wires) are underneath the solder mask. Not infrequently, blue or even red solder masks are used.

By Lydie Honorine. Circuit. Published at Tuesday, December 26th 2017, 04:03:26 AM. 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 Jessica Mireille. Diagram. Published at Tuesday, December 26th 2017, 02:59:42 AM. A schematic shows connections in a circuit in a way that is clear and standardized. It is a way of communicating to other engineers exactly what components are involved in a circuit as well as how they are connected. A good schematic will show component names and values, and provide labels for sections or components to help communicate the intended purpose. Note how connections on wires (or "nets") are shown using dots and non-connections are shown without a dot.
