1. Build the circuit shown above, and:
2. Rotate R2 adjustment knob fully CCW (counter clockwise); measure the circuit current and recor d
the reading.
3. With R2 adjusted fully CCW, measure the voltage drops across the resistors and record the readi ngs.
4. Rotate R2 to fully CW (clockwise) and measure the current; record the reading.
5. With R2 adjusted fully CW, measure and record the voltage drops across the resistors.
