Question

Answer 5-9 please Suppose you are sitting in a car and a 20-kV power line drops across the car. Should you stay in the car or get out? The power line potential 20 kV compared to the potential of the ground. Why is it dangerous to touch the terminals of a high-voltage capacitor even after the voltage source that charged the battery is disconnected from the capacitor? What can be done to make the capacitor safe to handle after the voltage source has been removed? Use the atomic theory of matter to explain why the resistance of a material should increase as its temperature increases. In an analogy between traffic flow and electrical current, (a) what would correspond to the charge Q? (b) What would correspond to the current /? Two lightbulbs are each connected to a voltage of 120 V. One has a power of 25 W, the other 100 W. Which lightbulb has the higher resistance? Which lightbulb carries more current?

Explanation / Answer

5)Stay in since touching anything metal would electrocute you

6)It is still charged and therefore has a potential difference across it. b)A resistor can be connected to it to discharge it.

7)Energy of electrons increases. randomness increases. Systematic flow in a given direction more difficult.

8)Q=number of cars on the road.

I=average speed of those cars

9)25 W has higher resistance

b)100W carries higher current
