An electromagnet can be created by passing an electric current through a coil of wire.

The movement of electrons through a conductor is called _______________

All circuits should be treated as live (energized) until they are proven to be dead (de-energized)

A ohmmeter is used to check the continuity of a circuit.

A device that is designed to de-energize a circuit when a current imbalance between the hot and neutral in excess of .006 amperes is detected is called a(n)  ___________

If 240 volts is applied (L1 to L2) to the circuit below, what voltage should you read across the start button.  Assume all devices are  in the state shown.

If the resistance of a circuit is 24 ohms and the current flowing in the circuit is 10 amperes, what voltage is being supplied to the circuit? 

Based on the 3 point pressure system, identify the affect compartment being unloaded by the knee orthosis pictured.  

Physical evaluation of a pediatric CP patient reveals an R1 of -5 (5 degrees PF) and a R2 of WNL (full range).  Select below the most likely posture of the tested ankle in midstance. 

Select below the recommended treatment for a Grade I-II sprain of the LCL. (HINT:  Gary Bedard explains in the Determination of Knee Center video how the knee goes into 7-11 degrees of valgus at full extension and at 25 degrees of flexion incurs a varus moment)
