Consider the three basic quantities of a circuit: voltage (potential difference), current, and resistance. In general terms, describe each one in your own words and its basic characteristic/property, and can you do an analogy of these quantities with a fluid system, say a stream of water? Further, since many of you are in the medical field, can you relate a basic circuit and its components to a system of the body, maybe the circulatory system? If, what is the analogy...

Why do the voltage and current in the pickup coil cycle between negative and positive? Explain in detail using Faraday’s Law. Remember, Lenz’s Law is part of Faraday’s Law! Although it will not be covered explicitly in this class, this is known as alternating current. Points to discuss: How the magnetic flux through the loop changes as the magnet rotates. Is the flux maximal when the magnet is horizontal or vertical on the screen? Why?) How this changing magnetic flux...
