1. The manufacturer rated these capacitors at the following values: Capacitor Rated Value
uF
1 100
2 220
3 330
4 390
5 470
6 680
Compare your experimental value of C to the rated value.
Probably you'll notice that your measured value is a little bit different to the one listed above. Let's think about where this error comes from. Below, we've suggested three potential sources of error that might result in your measurement being slightly off from the correct value.
The capacitors have an equivalent series resistance. This resistances increases the effective R of the circuit.
The Analog meter does not react fast enough to the circuit.
The value of C that the manufacturer rated the capacitor for is too high
2. First state if your measurement over or underestimated the rated value of the capacitor.
For each source of error we identified above, state whether that effect would cause your measurement to be larger or smaller than the capacitor's actual value.
Hint: Discuss each source given and number it your answer should be similar to___.
The equivalent resistance my measurement which is supported by___.
