Homework Statement
This is a lab problem and basically I am supposed to explore the properties of a capacitor.
instructions said:Charge capacitor C1 up to some voltage V1 (less than 5V) and disconnect the capacitor from the supply. Measure the voltage with the bench voltmeter and record.
C1 = 3300uF
V1 = 4.50V
Supply Voltage = 4.50V
Here is the question that confused me
Is the voltage reading steady? Why might you expect this voltage to vary?
My DC supply 4.50V was the same as I measured it. But I forgot what I was measuring. Does it make sense if I clamp my capacitor with the voltmeter and measure the voltage of a capacitor? I am thinking it doesn't because I have a capacitance, not voltage.
If so what was I measuring? I don't think it would make sense to measure the DC Supply with a voltmeter...
Why would the reading not be steady?
