# How do you use current markers in PSPICE?

## How do you use current markers in PSPICE?

Voltage and current markers are used to probe the voltage or current. After simulation, PSPICE automatically plot the results. Select Markers/Mark Voltage/Level [Ctrl+M] or click voltage marker icon to place the voltage marker. Select Markers/Mark Current into Pin or click current marker to place the current marker.

**What is dependent and independent voltage source?**

Independent source are those, whose value of either the voltage or the current to be delivered is independent of any other parameter of the network. Where as the dependent sources are those, whose value of either the voltage or the current to be delivered is dependent or controlled on other parameters of the network.

### Where does the current come from in PSpice?

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.

**Can you check the node equations with PSpice?**

The node equations can be checked by determining the values of the node voltages using PSpice and substituting those values into the node equations. PSpice does not calculate mesh currents, but it does calculate the currents in voltage sources.

## How is PSpice used to analyze a circuit?

PSpice can be used to analyze circuits that contain dependent sources. The PSpice symbols used to represent dependent sources are labeled as E, F, G, and H (see the table to the right) and are located in the analogy library. Part 2A: Capturing and Simulate a CCCS Circuit

**How is the mesh current calculated in PSpice?**

PSpice does not calculate mesh currents, but it does calculate the currents in voltage sources. The mesh current i2 is the current through the 12 V voltage source. PSpice uses the passive convention for all elements, including voltage sources. The voltage source current that PSpice will report is the current direction from + to −.
