Chapter 9.9 Voltage

Slide 1 - Tekstslide

What is voltage(potential difference)
Voltage is the force that pushes charges (electrones) to move around a circuit. 
In other words, it is the amount of energy given to the components in a circuit from the electrons passing through the wire. 

Slide 2 - Tekstslide

Measuring voltage
Voltage is measured in volts using voltmeter (V)

Slide 3 - Tekstslide

Voltmetes are connected in parallel not in series like ammeters

Slide 4 - Tekstslide

Slide 5 - Tekstslide

Slide 6 - Tekstslide

Voltage in serie and parallel  circuits 

Slide 7 - Tekstslide

The voltage is divided between the two lamps. In series circuit.

Slide 8 - Tekstslide

The voltage remains the same. Each lamp gets the same amount of voltage if the lamps are equal.

Slide 9 - Tekstslide

Slide 11 - Link

What are the readings on ammeters A2 and A3
 if the reading on  A1= 0,5 A?

a. 1A    2. 0.5 A    3. 0.25 A

Slide 12 - Tekstslide

What are the readings on ammeters A2 and A3
 if the reading on  A1= 0,5 A?

a. 1A    2. 0.5 A    3. 0.25 A

Slide 13 - Tekstslide

What is the reading on voltmeter v1
 if the reading on v2 =9v 
 and v3 = 3 v?

Slide 14 - Tekstslide

What is the reading on voltmeter v1
if the reading on v2 =9v and v3 = 3 volt?
12 v

Slide 15 - Tekstslide

What are the readings on v2 and v3 
 if the reading on v1 =12 v?

Slide 16 - Tekstslide

What are the readings on v2 and v3 
 if the reading on v1 =12 v?
v2 = 12 and v3 =12
