Data Collection: Transformers

Select $$Transformer$$ along the top.

$1.$ Move the smaller, left, powered, primary coil close to or inside the larger, secondary coil.

Why is no current generated in the secondary coil?

$2.$ Now toggle the Current Source from DC to AC$.$

Why is current generated in the secondary coil now?

$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

$3.$ 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 $.$

As frequency decreases $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

and as frequency increases $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$
