6 FAQs about [Capacitor reading experiment results]
How can a coulomb meter be used to test a capacitor?
Two experiments are possible; this one makes use of a coulomb meter. By charging a suitable capacitor to different voltages and measuring the charge stored each time, you have a rapid confirmation of the relationship Q ∝ V. The experiment can be repeated with different capacitors. Plot a graph of Q against V.
