When Canvas Goes Down: VCCS Builds a Plan Virginia's Community Colleges July 1, 2026 0 Comment

Welcome to VCCS Platform Your personalized career counseling solution. Discover your potential and shape your future with AI-powered guidance.

Virginia’s Community Colleges (VCCS) have a 50-year track record of educational excellence and innovation to serve the needs of our citizens and strengthen the commonwealth’s economy.

Voltage Controlled Current Source (VCCS) Circuit: An ideal form of a current source, whose output current I out is controlled by an input voltage is shown in Fig. 36.35.

Figure 2 (right) shows the per-unit voltage and current at the VCCS terminals. In this example, H (z) and the time constants have been chosen to provide clear illustration of their impacts; these are not necessarily typical values for a real inverter.

This tutorial runs through an example with a Voltage Controlled Current Source (a dependent power source). We start by finding the controlling voltage, and t...

Figure 3. Voltage Controlled Current Source (VCCS) 4. Current Controlled Current Sources (CCCS) Current control current source, as shown in Figure 4, the current of the controlled current source is: i2=βi1, where β is the dimensionless current control coefficient or current gain.

Here, you can see a very simple and basic circuit diagram of VCCS. We just take a field-effect transistor where a controlling voltage source is shown on the gate terminal side and the controlled current source is shown in the source and drain terminal.

A voltage-controlled current source (VCCS) is a dependent source that produces an output current proportional to a controlling voltage, usually written I = kV. In Intro to Electrical Engineering, you use it to model circuit behavior and small-signal devices.
