In the circuit to the right there are two dashed lines. Can Kirchoffs loop rule be used on either one? Both?

There are also two small circles. Can Kirchoffs junction rule be applied at one or both of these locations?

How many possible loops and junctions can you spot in this circuit?

A 1 mF capacitor is charged up to 2500 V and then allowed to discharge through a 500 k resistor. Estimate how long it takes before the voltage across the capacitor has dropped to a safe value.

Note: this is one reason why you should NOT poke around inside a TV set if you do not know what you are doing.

When connencted in parallel, 1/R_T=1/R₁+1/R₂+1/R₃+... . Similar to adding capacitors in series. On the other hand, resistors in series are added like capacitors in parallel. In a few sentences, explain why this is true.

You might try to discharge a capacitor through a lightbulb, in order to "see" the exponential decay of the current by observing the decreasing brightness of the bulb. Using a 0.5 ohm flashlight bulb, estimate how large a capacitor you would need to observe this phenomenon conveniently. Is this a reasonable thing to try?
