Question: The answers to R3a and DA3a should be similar. However, the answers to R3b and DA3b should be different in one important aspect. Use the Faraday's Law equation to explain why the frequency has this different effect on the two coils.

R3a: What effect does the amplitude setting have on voltage/current in the small coil of circuit 2?

When the amplitude is increased, the voltage spikes are increased. While decreasing the amplitude causes a decrease in voltage spikes. The is no change of the current.

R3b: What effect does the frequency setting have on the voltage/current the small coil of circuit 2?

When increasing or decreasing the frequency, there is no affect on the voltage. When the frequency was increased, the current decreased. The frequency is indirectly propotional to the current.

DA3a: What effect does the amplitude setting on the function generator have on Oscope display of the voltage in the big coil?

Increasing amplitude increases voltage on the oscope display.

DA3b: What effect does the frequency setting on the function generator have on the Oscope display of the voltage in the big coil?

Increasing frequency increases voltage on the oscope display.
