1. At what position is the induced emf 0 V? Why?
2. At what position is the induced emf maximum? Why?
3. Why does the induced current change direction?

Link

1. Choose "Oscilloscope".
2. Increase the wind strength (frequency of rotation).

How does the induced emf change when the frequency of the rotation increases? Why?

ONLY USE THE CIRCUIT ON THE LEFT (ignore the right circuit)

TASK 1

1. Start with the switch up, not connected to the battery. (default). The current should be 0.
2. Press "switch" so that the circuit is connected to the battery.

What happens to the current?

Why does the current not increase to its maximum value instantly?

TASK 2

1. Start with the switch down, connected to the battery. The current should maximum.
2. Press "switch" so that circuit is disconnected from the battery.

What happens to the current?

Why does the current not drop to 0 instantly?

ONLY LOOK AT THE LEFT CIRCUIT (ignore the circuit on the right)

The simulation show two voltages. Supply voltage V0 and the induced voltage V in the coil. Observe these two voltages.

Task 1

1. Increase the frequency of the AC supply voltage

What happens to the maximum current generated? Why?

What happens to the induced voltage in the coil? Why?

Task 2

What can you say about the relative timings of Vo and V?

When is the induced voltage V maximum/minimum? Why?

When is the induced voltage V equal to 0? Why?
