Capacitor Voltage-Current Relations
We sketched capacior voltage and capacitor current sinusoidal wave and triangular wave using the capacitor voltage current relations. Because the current is equal to dv/dt, we anticipated the oscilloscope to detect Voltages and currents as such:when current is positive , voltage is negative and vise versa.
The dispay date for C1(top) A=1.032V the signal for the input voltage, C2(under) A= 1.626V the voltage across the capacitor, M1(mid) the current through the resistor, when f=1kHz, A=2V, and Offset=0V
The dispay date for C1(top) A=1.452V the signal for the input voltage, C2(under) A=1.178V the voltage across the capacitor, M1(mid) the current through the resistor, when f=2kHz, A=2V, and Offset=0V
The dispay date for C1(top) the signal for the input voltage, C2(under) the voltage across the capacitor, M1(mid) the current through the resistor, when f=100Hz, A=4V, and Offset=0V
Here we see the circuit wired up with wires connected for ground and measuring channels for the Analog Discovery.
Summary: The first graph shows a how current and voltage increase and decrease in the same time frame. The second graph's voltage and current graphs are more condensed than the first ones' due to higher frequency values. The third graph shows how linear increasing and decreasing of voltage results in flat lines for the current graph.
