Current requirements of various devices

This table shows what happens when we put a resistor in series with a device (as shown in the diagram).

a resistor in series with a device

Device R = 10 Ohm R = 100 Ohm R = 1000 Ohm R = 10000 Ohm
LED

 

       
Buzzer

 

       
Motor

 

       
Light bulb

 

       

Interpret the table: how much current does each device need? (Note that the resistor limits the current to 3V/R).

 

 

 

 

By comparing this table to the one from the previous activity, what can you say about the resistances of the objects you studied there?
