Quiz zum Vortrag
You insert a dielectric of dielectric constant k = 2 into a capacitor with a dielectric constant of k = 1, connected to a battery. What will happen to the capacitance, charge, and energy stored in the capacitor, respectively?
- Capacitance doubles, charge doubles, and energy doubles
- Capacitance doubles, charge reduces to one-half, and energy doubles.
- Capacitance doubles, charge multiplies by 4, and energy multiplies by 4.
- Capacitance doubles, charge doubles, and energy multiplies by 4
- Capacitance doubles, charge reduces to one-half, and energy reduces to one-half
A charged capacitor disconnects from a battery. What happens if you insert a dielectric of dielectric constant k = 2 into the capacitor with a dielectric constant of k = 1?
- The capacitor's charge remains the same, but its energy reduces to one-half.
- The capacitor's charge and energy remain the same.
- The capacitor's charge and voltage reduce to one-half.
- The capacitor's voltage reduces to one-half, but its energy remains the same.
- The capacitor's charge and capacitance multiply by 2.
What happens if you connect a capacitor of charge Q = 0 and capacitance C to a battery of voltage V?
- Electric charges will build on each plate, approaching the value of CV.
- The capacitor discharges into the battery.
- The battery puts energy CV on the capacitor.
- Charge flows until the capacitance slowly reaches C.
- Voltage begins to build up until reaching a value of CV.
