1: Pracitce with resistance power and voltage … low difficulty

2: Resistors in series and parallel … low moderate difficulty

3: Good conceptual question. Connects with biology. Low moderate difficulty.

4: Standard two loop Kirchoff's law problem. Moderate difficulty

5: low to moderate difficulty conceptual question to try to make RC circuit concepts sink in.

6: moderate difficulty RC circuit problem

Typically this material is relatively simple … sometime tedious. That's why there is nothing all that difficult on the module. If you go to the difficult problems sometimes they are quite hard to see ….and little is gained pedogogically.
