Example Question #3 : Electricity And Magnetism
A capacitor with capacitance is constructed by putting a thin piece of cardboard between two copper plates, then each plate is connected to a battery. If the copper plates are cut in half then what is the effect on the capacitance of the circuit?
Possible Answers:
Correct answer:
Explanation:
Capacitance of a circuit is defined by the equation:
Where is the capacitance, is a constant of nature, is the area of the capacitor, and is the distance between the two plates
Since the metal plates are cut in half, the area is halved. We can substitute in for
The result is that the capacitance is half the original quantity.
