EM1.3 Red ELRC Board
This is a big board with an indicator, capacitor and resistor mounted on it. The voltage across each component may be displayed on an oscilloscope which the class can see on the monitors (see CAMERA). Begin with a DC component input into the board. Let the class notice the effect of changing the component. Then input the AC current. Each device has an on-off switch. By placing an output to Channel 1 which represents to the input current and the other on Channel 2 which represents the output voltage, the class can see the phase difference across different components, or combination of components.
