5. Slow the AC Current Supply down by sliding the frequency switch to the left (5%). Name the wave: cosine wave. (1 mark) Why is no current generated in the secondary coil? (1 mark)
2. Now toggle the Current Source from DC to AC. Alternating current is induced in the second coil. 3. Now toggle the Pickup Coil Indicator from bulb to voltage meter. Now vary the frequency from 5% to 100%. Describe the relationship between frequency and current flow (or voltage as from the voltage meter) in the secondary coil
Select “Generator” along the top. 1. Adjust the water flow on the faucet so the generator rotates at 20 to 25 RPM. Examine the power generated in the coil. What kind of current is being generated?
2. Vary the number of Loops in the coil. Make a statement that relates the number of coils to the amount of power generated. (1 mark)
3. The spinning magnet is called the stator. If the water flow ceased and you supplied power to coil causing the stator to spin you would then have a motor instead of a generator. (1 mark)
