## What is voltage source and current source?

A Source is a device which converts mechanical, chemical, thermal or some other form of energy into electrical energy. A voltage source has a forcing function of emf whereas the current source has a forcing function of current. …

**What is current source example?**

A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it. A current source is the dual of a voltage source….Background.

Controlled voltage source | Controlled current source |

**What is the difference between voltage and current?**

Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. Resistance is a material’s tendency to resist the flow of charge (current).

### How does pspice measure voltage gain?

In order to determine the differential gain (in theory or in PSpice), you must put in a pure differential AC input (Vin1 = -Vin2). Then the differential gain is computed as Vout/(Vin1-Vin2). In order to determine the common-mode gain, you must put in a pure common-mode input (Vin1 = Vin2).

**What do you mean by voltage source?**

A voltage source is a two-terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. A voltage source is the dual of a current source.

**What is relation between voltage and current?**

The relationship between voltage, current, and resistance is described by Ohm’s law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.

## What is a piecewise linear voltage source?

The piece-wise linear voltage sources allow you to describe a transient voltage waveform by connecting time-voltage pairs, which you define. The following are schematic parts that can be used, along with their property definitions: Name: VPWL. Use: Piece-wise linear voltage source.

**What does PSpice stand for?**

not present Dependent Source Abbreviation PSPICE Name Voltage Controlled Voltage Source VCVS E Current Controlled Current Source CCCS F Voltage Controlled Current Source VCCS G Current Controlled Voltage Source CCVS H

**What are part properties in PSpice help?**

Also of interest: Part Properties in the PSpice Help defines all of the user-defined properties on the PSpice schematic parts, and is a help to know which properties to set on the xPWLx symbols in the SOURCE libray.
