For question 17, multiple options possible.

Total 41 points.

Mark = amount / 41 *9+1

TIME.... FOR A QUIZZZZZZ

Go and sit in pairs

You might need a paper to write on & a calculator

RULES FOR THE QUIZZZ

1. You only whisper in your duo about your answer
2. You may celebrate your victory, however mind the volume
3. Use your brains :)
4. There might be a prize involved...
5. GOOD LUCK 

Will you have fun during the quizz???

😒🙁😐🙂😃

The particle of a molecule, is called a(n)...

1. Atom
2. Electron
3. Proton
4. Neutron

What is the atomic property of a conductor?

1. All electrons want to stay close to the core
2. All protons want to stay close to the core
3. Some electrons will jump over to the next atom
4. Some protons will jump over to the next atom

What is this component?
(as called in the reader)

Electric current is the flow of...

1. Resistance
2. Charge
3. Ampère

Increasing the number of connected batteries in a series circuit, it .... the current.

1. Increases
2. Decreases
3. Does not affect

True or false:
The current measured by ammeter 1 would be the same as ammeter 2.

1. True
2. False

What is this component?
(as called in the reader)

Ammeter A1 reads a current of
0.4 Ampère.
What is the current of meter A2?
!!Only note the NUMBER!!

Voltmeter V1 reads a voltage of 6 V.
What is the voltage over the light bulb?
!!Only note the NUMBER!!

The light bulb is wired in [1];
The volt meter is wired in [2]

1. [1] = parallel [2] = series
2. [1] = parallel [2] = parallel
3. [1] = series [2] = parallel
4. [1] = series [2] = series

How are you all doing?

😒🙁😐🙂😃

V1 reads 8 volts. Assuming these are 2 of the same light bulbs, what is the value measured by V3?

1. V3 = 8 V
2. V3 = 4 V
3. V3 = 16 V
4. V3 = 2 V

This is the symbol for...

Assume that all light bulbs have the same resistance.
A1 reads 1.5 Amps.
What does A3 read?

1. 0.75 A
2. 3 A
3. 1.5 A

How do you calculate resistance when you have the voltage and current?
Use the symbols, no spaces.

Lisa wants to calculate the resistance of the lower bulb, next to A4.
One battery supplies 9V, the ammeter A4 reads 0.75 A.
Calculate the resistance, only note the answer in numbers!

2* 9V = 18V

R =U/I

R= 18/0.75 = 24 Ohm

A component in a circuit has a current of 250 mA flowing through it. The resistance of this component is 40 Ohms.
What is the voltage used to power the component?

1. 10.000 V
2. 1000 V
3. 100 V
4. 10 V

Given:

R = 40; I = 250 mA = 0.25 A

Asked: U in V

R = U/I --> U = R * I

U= 0.25 * 40 = 10 V

This is the symbol for...

1. Fuse
2. Resistor
3. Diode
4. Thick wire

What type of circuit is this?

1. Series
2. Parallel
3. Mixed
