Question 1

1.

Mastery checks are pledged activities. You may ONLY use: a calculator. No assistance from notes, friends, the internet, etc.
You may write "I pledge" and sign your name here.

Question 2

2.

What is the value of the voltage from this voltmeter? Type just the number into the answer blank.

Question 5

5.

For this circuit, you will need the following materials:
1 D battery in a case
1 lightbulb in a holder
1 ammeter
1 voltmeter
wires
alligator clips
Build the described circuit and when it is done, demonstrate it to your teacher, and they will check it off in Formative.

Build a circuit with a battery and a lightbulb. Insert an ammeter to measure the value of the current through the lightbulb and a voltmeter to measure the value of the voltage across the lightbulb.

Write down the measured values of the voltage and current in your circuit.

Categorize each of the statements as to whether it belongs to an ammeter a voltmeter or neither. If it applies to both, then put it in both categories. 

used to measure the voltage across an element in a circuit

used to measure the current through a circuit element

used to measure the power of a circuit element

always placed in parallel (outside with the cables touching either side of the circuit element)

always placed in series (interrupting) with the rest of the circuit

does not matter where it is placed in the circuit

Ammeter

Voltmeter

Neither

A student is designing a circuit to measure both the current through a lightbulb and the voltage across a lightbulb. Here is the diagram the student came up with. What is wrong with the diagram? Choose the best answer.

The lightbulb will not light up in this configuration, so you are not measuring anything in this case.

The voltmeter and ammeter are in the wrong place. They should be switched. 

The voltmeter is in the wrong place. It is measuring the voltage of the wrong thing. 

The ammeter is in the wrong place. It is measuring the current of the wrong thing.
