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 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
