Diode-fare semiconductor devices. Diodes only allow a current to pass in one direction in a circuit (forward direction).
The potential difference (p. d.) at which the diode will allow a current to pass in the
circuit is called the threshold p. d.
Write a plan to find the threshold p. d. and its direction to enable a current to pass.
Your plan should include the following details:
a hypothesis
selection and justification of equipment, techniques or standard procedures
health and safety associated with the investigation
methods for data collection and analysis to test the hypothesis including:
the quantities to be measured
the number and range of measurements to be taken
how equipment may be used
control variables
brief method for data collection analysis.
