Notice that a parallel-connected motor delivers performance identical to a series-connected motor running at twice the power supply voltage.

In a digital circuit, power supply voltage levels are constrained to two distinct values – “logic high voltage” (called LHV or Vdd) and “logic low voltage” (called LLV or GND). The GND node in any circuit is the universal reference voltage against which all other voltages are measured (in modern digital circuits, GND is typically the lowest voltage in the circuit). In a schematic, it is often difficult to show lines connecting all GND nodes; rather, any nodes labeled GND are assumed to be connected into the same node. Often, a downward pointing triangle symbol, is attached to a GND node in addition to (or instead of) the GND label. The Vdd node in a digital circuit is typically the highest voltage, and all nodes labeled Vdd are tied together into the same node. Vdd may be thought of as the “source” of positive charges in a circuit, and GND may be thought of as the “source” of negative charges in a circuit. In modern digital systems, Vdd and GND are separated by anywhere from 1 to 5 volts. Older or inexpensive circuits typically use 5 volts, while newer circuits use 1-3 volts.

Voltage nodes are single-terminal schematic components, which we can connect component terminals to in order to assign them to a specific voltage level. These are a special application of net names, meaning all terminals connected to a like-named voltage node are connected together.

In series regulation the control element is placed between the unregulated voltage source and the load and the current through the element is controlled so that the voltage across the load is held constant. A feedback control system is used where the difference between the output voltage and a reference voltage is applied to a high gain amplifier that drives the current control element such as to maintain the setpoint output voltage. The majority of voltage regulators are of the series type.

By Madeleine Catherine. Diagram. Published at Thursday, October 12th 2017, 12:26:33 PM. When working with circuits, you will often find something called a schematic diagram. These diagrams use symbols to illustrate what electronic components are used and where they’re placed in the circuit. These symbols are graphic representations of the actual electronic components.
By Valentine Sybille. Circuit. Published at Tuesday, October 10th 2017, 11:14:52 AM. In the hydrodynamic analogy of electronic circuits, resistors are equivalent to a pipe. As fluid flows through a pipe, frictional drag forces at the walls dissipate energy from the flow and thus reducing the pressure, or equivalently, the potential energy of the fluid in the pipe. A small resistor is equivalent to a large diameter pipe that will allow for a high flow rate, whereas a large resistor is equivalent to a small diameter pipe that greatly constricts the flow rate.

This is a set of multiple electronic circuits on a small semiconductor device (normally silicon). With the advancement of technology, these IC’s prove to be extremely beneficial. They are present in any electronic device you can name. From computers, mobiles to other digital appliances you have multiple IC’s present in them. Their main components are a combination of Diodes, transistors and microprocessors. The microprocessors provide memory to the device. With the help of the microprocessor the electronic devices can perform logical or protocol applications.
