# Plot I-V Curve

Here we plot voltage across an element against the current flowing though it. The current is calculated from the voltage across a series resistance. The graph of resistors is a straight line, but not for non-linear elements like the diodes.

# Objective

Plot the I-V curve of several circuit elements.

# Procedure

- Connect the resistors as shown in the figure.
- R2 is used for measuring current, generally 1000Ω
- Current through the circuits is Voltage at A1 / R2
- PV1 is varied is steps. Voltage across R1 with current is plotted
