- Calculate the resistance between points
**A**and**B**for the following resistor networks: - From this circuit (with components attached to a “terminal strip”), draw an appropriate schematic diagram. Then explain the function of the resistor and what happens when the pushbutton is pressed (assuming it is normally open).
- Complete the table of values for this circuit:
- Draw a schematic for the following:
- Considering your two inputs (A and B) in the image below, what type of logic is used to actuate the coil of CR3? Lamp 1? Lamp 2? If Lamp 2 never turns on, what components of the circuit could be causing the problem?
- Create a truth table for the following diagram:What conditions must exist in order for the light to energize?
- Create a simplified schematic for the following complex circuit:
- Complete the table for the following schematic: Express all current in milliamps.
**R1****R2****R3****R2 // R3****Total****E**48 V **I****R**120 Ω 120 Ω 200 Ω - Create a truth table for the following diagram: What conditions must exist in order for the light to energize?
