1. How does the charge on one plate of a capacitor compare with that on the upposite plate?

2. Why is that you are safe from a lightning storm if you are inside an automobile?

Do some thinking about your various questions and someone will be glad to comment.

Cutting and pasting questions and answers is a poor way to learn physics

1. The charge on one plate of a capacitor is equal in magnitude but opposite in sign to the charge on the opposite plate. To understand how the charges on the plates of a capacitor are related, we can consider the process of charging a capacitor. When a voltage source is connected to the plates of a capacitor, one plate becomes positively charged and the other plate becomes negatively charged. This happens because the voltage source causes electrons to flow from one plate to the other, creating an excess of electrons on one plate and a deficit of electrons on the other. This separation of charges creates an electric field between the plates. The magnitude of the charge on each plate is equal, but the signs are opposite, ensuring that the net charge of the capacitor system is zero.

2. Being inside an automobile provides a degree of safety during a lightning storm due to the concept of the "Faraday cage." A Faraday cage is a conductive enclosure that can shield its interior from external electric fields. When lightning strikes, it creates a massive discharge of electrical energy. The exterior metal body of a car, acting as a conductor, helps to distribute the electrical charge evenly across its surface. This causes the electric field inside the car to be nearly zero, protecting the occupants. In addition, the tires of the car act as insulators, preventing electric current from passing through the vehicle and keeping the occupants safe. However, it's important to note that although being inside a car can offer some protection, it's still best to avoid driving during a lightning storm if possible.
