Large=180

medium= 60

small= 45

 

1.) Which circuit had the largest current?

The circuit with the large bulb had the largest current, 180mA

 

2.)Which circuit had the smallest current?

The circuit with the long bulb had the smallest current, 45mA

 

3.)What is the purpose of the switch in this current?

The purpose of the switch is to turn to light off and on

 

4.)When you measure an unknown current, you should start with the meter set to a large current scale and then decrease the scale. Explain the purpose of starting with a higher setting.

You should start with a higher setting because if you start with a small setting you could overload the meter and end up braking it because then current could be too high. If you start with a higher setting then you can work your way through the smaller settings until it is easy to get an accurate reading.
