How are dependent sources used in a circuit?
Dependent sources As we begin to use simple circuits to model more complex circuit behavior, we need to add some items to our tool kit. Dependent sources behave just like independent voltage and current sources, except that the voltage or current depends in some way on another voltage or current in the circuit.
What are the two types of dependent current?
There are two types of dependent current source – the voltage controlled current source (VCCS) and the current controlled current source (CCCS). These sources are mathematical models that are useful in modelling real circuits and systems, e.g. they are used in modelling transistors.
Which is an example of a current divider?
Current Divider Examples Current Divider for 2 Resistors in Parallel With Current Source. Example 1: Consider two resistors 20Ω and 40Ω are connected in a parallel with a current source of 20 A. Find out the current flowing through each resistor in the parallel circuit. Given data: R 1 = 20Ω, R 2 = 40Ω and I T = 20 A
When do you use the current divider rule?
The Current divider rule can also be used to determine individual branch currents when the total circuit current and the equivalent resistance are known. When two resistors are connected in a parallel circuit, the current in any branches will be a fraction of the total current (I T) ).
Solutions for circuits using dependent sources follow along the lines of those established for independent sources (i.e., the application of Ohm’s law, KVL, KCL, etc.), however, the sources are now dependent on the remainder of the circuit which tends to complicate the analysis.
Which is a dependent source of PSpice voltage?
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 is the value of a dependent source?
A dependent source is a current or voltage source whose value is not fixed. Instead, the value depends on some other circuit current or voltage. The general form for the value of a dependent source is N = k M where M and N are currents and/or voltages and k is the proportionality constant.
Where does the current go in a PSPICE circuit?
PSPICE Schematic with Current Controlled Voltage Source Note that the right side of the device goes where the voltage source appears in the circuit. The left side is connected so that the controlling current (in this case I 0 ) runs through the left side of the dependent source symbol.
