Lab Day 13

Capacitor Voltage-Current Relations Lab

In this lab assignment, we measured the relationship between the voltage difference across a capacitor and the current passing through it. We applied several types of time varying signals to a series combination of a resistor of 100 ohms and a capacitor of 1 microF. The voltage difference across the resistor, provided an estimate of the current through the capacitor. This current can be related to the voltage difference across the capacitor. 

This is a picture of the circuit.

This is the pre-lab. The top graph shows a sinusoidal wave of the capacitor voltage and current. The bottom graph show a triangular wave of the capacitor voltage and current.

This is an image of the capacitor current for a 1kHz sinusoidal input. 

This is an image of the capacitor current for a 2kHz sinusoidal input. 

This is an image of the capacitor current for a 100Hz triangular input. 

This is an image of the math channel to calculate current from resistor's voltage for a 1kHz sinusoidal input.
