Voltage Flashcards
Also known as Potential Difference
Voltage
The force (pressure) that causes current to flow
Voltage
IS A MEASURE OF HOW MUCH ENERGY THE ELECTRONS RECEIVE.
VOLTAGE
Voltage is measured in
volts (V)
The battery provides ——— that will push current through the bulb when the switch is on.
voltage
The difference in potential energy between two locations.
Potential Difference
Positive =
Negative =
High Potential Energy
Low Potential Energy
• The difference between a rollercoaster and an electric current is that the potential difference is caused by the ——— in two locations, not height.
difference in electrical charges
Electric charges will always flow from a region of ——— potential energy to a region of
——— potential energy.
high
low
•When the charge reaches the positive terminal and enters the battery, it ——— electric potential energy as it travels through the battery to the negative terminal.
Gains
Voltage is measured using a ————
voltmeter
A voltmeter must be connected in ——— as it measures the potential difference across the component.
parallel
When two or more circuit components are connected in series the total voltage of the supply is ——- between them.
shared
The voltmeter should be connected across the load being tested. The ——— terminal of a voltmeter is connected to the ——— terminal of the bulb while the ——— terminal is connected to the ——— of the bulb.
positive, negative
The symbol for Voltage is
(V)
