CONTROLS:
- Choose one of the 7 resistors.
- Connect the black probe by dragging the circular end to the appropriate multimeter input and dragging the other end to make contact with the resistor.
- Connect the red probe by dragging the circular end to the appropriate multimeter input and dragging the other end to make contact with the resistor.
- Press the yellow dot on the edge of the multimeter selector and stop to the appropriate ohmmeter scale.
DESCRIPTION OF THE SIMULATION:
This simulation allows studying the ohmmeter function of a digital multimeter. In the simulation only the ohmmeter function is active. The resistance value of the resistors can be determined using the color code and the measurement can be verified with the ohmmeter. The measured values may vary (within the tolerance of each resistor) with each new simulation restart.
For an analysis of the data, consult one of the proposed ACTIVITY GUIDE.
