The following V-I characteristics are data for two devices:
1. Plot the data in a spread sheet program
2. State which device is ohmic and non-ohmic, give your reasons.
3. For the Ohmic device, give is resistance
4. The devices are placed in series with an ammeter and a variable power supply. Draw the circuit.
5. If the ammeter reads 12 mA, what if the power supply voltage reading?
6. The components are now placed in parallel with an ammeter next to the supply. Draw the circuit.
7. If the power supply is set to 5.0 V, what is the current reading on the ammeter? (use the forward trend line in excel)
