Capacitors Online Test – Multiple Choice Questions and Answers 1. A capacitor stores energy within a dielectric between the conducting plates in the form of: an electric field positive voltage a magnetic field negative voltage 2. A capacitor is constructed of two parallel: dielectrics inductors conductors semiconductors 3. Which of the following determines the capacitance of a capacitor? Plate area, dielectric strength, and plate separation Plate area, dielectric constant, and plate separation Temperature coefficient, plate area, and plate separation Voltage rating, dielectric constant, and temperature coefficient 4. In an ac circuit, an output capacitor and a resistor are connected in series with an ac signal. What filter action will be the result? bandpass low-pass high-pass band-stop 5. After which time constant can a capacitor be considered to be fully charged? first third fifth seventh 6. If an open capacitor is checked with an ohmmeter, the needle will: stay on zero move from zero to infinity stay on infinity move from infinity to zero 7. When is a capacitor fully charged? when the voltage across the plates is 0.707 of the input voltage when the current through the capacitor is the same as when the capacitor is discharged when the voltage across its plates is 1/2 of the voltage from ground to one of its plates when the current through the capacitor is directly proportional to the area of the plates 8. Most older types of paper capacitors have been replaced by which type of construction? electrolytic waxed paper oxide casing plastic film 9. You could increase the time constant of an RC circuit by exchanging the position of the resistor and capacitor in the circuit increasing the amplitude of the input voltage adding a resistor in parallel with the circuit resistance adding a capacitor in parallel with the circuit capacitance 10. A capacitor’s rate of charge is considered: exponential a current block magnetic linear Loading … Question 1 of 10
