Fill in a T/F answer for each statement below:
1. [ ] The equivalent capacitance of a parallel combination of capacitors is always
greater than any of the individual capacitance.
2. [ ] The equivalent capacitance of a series combination is always less than any
individual capacitance in the combination.
3. [ ] A good battery has a small internal resistance, and a weak battery has a large
internal resistance.
4. [ ] The internal resistance of a battery lowers its usable voltage.
5. [ ] The equivalent resistance of a parallel combination of resistors is always greater
than any of the individual resistors.
6. [ ] The Kirchhoff’s junction rule is based on the conservation of energy.
7. [ ] The Kirchhoff’s 2nd rule is based on the conservation of charge.
8. [ ] The time constant of an RC circuit is τ = 1/RC.
9. [ ] When charging an RC circuit, the voltage on the capacitor reaches 36.8% of its
maximum value at time = 1 time constant.
