What was the physical law you use to construct the graph in question 8

I said Faraday's Law.

I was thinking conservation of energy... )=

woops didnt see there was already a thread... )=

what did you guys do for the circuit.. i got thrown off

anyone want me to attempt solutions? i got an exam
Whatlol, I'd love to see the transmission questions worked out, after they make the final power 4W and you have to work back to find the voltage.

It would be Lenz's law..

it's gotta be lenz's law. negative gradient of flux change

Surely they should accept both Faraday's and Lenz's? They are both relevant to the graph.

I thought Lenzs law was just the direction? And faradays was that it was the gradient?

I said Faraday's law. Lenz's law only gives the direction of the current, not the magnitude of the induced EMF for each section of the graph.

Your graph had to start of negative and then go to positive.
For this, you would have to state Lenzs law.

I went with faraday's law. It was asking about the graph which faraday's law states is the negative rate of change of flux. How could it be lenz's?

Lenzs law adds the negative in front of the N, doesn't it? Otherwise it is faradays law...

Wouldn't be surprising if they accepted both.

I'm looking pretty good with the iTute answers so far...
