IV Characteristics

Question 1

what does it show when you measure the resistance through a fixed resistor?

Answer 1

Results show that this follows Ohms Law. The PD and Current are directly proportional

Question 2

what does is show when you measure the resistance of a filament bulb?

Answer 2

Results show that the filament bulb does not follow Ohms Law. As the current increases, the temperature of the bulb increases. This means that the resistance also increases, making it harder for the current to flow

Question 3

what can you see when you measure the resistance through a diode?

Answer 3

current will only flow through a diode in one direction. The diode has a very high resistance in the opposite direction
