Design a resistor combination. Using a 10.0V battery voltage and four 10 resistors (you can add switches to the diagram if needed), connect them in such a way to produce an equivalent resistance of

a) 2.5

b) 13.3

c) 10.0

d) 10.0 (a second way of making 10)

e) 7.5

For each case, you must use all four resistors.

Please draw a diagram for each case.
