Electricity and Energy Flashcards
What is potential difference?
The measure of energy given to the charge carriers in a circuit
What does V - I graph look like?
What is the voltage, current and resistance equation
What is the relationship between resistance and temperature?
As temperature increases the resistance decreases
What is the potential energy equation?
What is the kinetic energy equation?
What is kinetic energy measured in?
Joules
What else is released when potential energy is converted into different forms?
Heat
What is the equation for charge?
Q=IT
What is current?
The amount of charge carried by a conductor every second
What is the difference between AC and DC
In AC the charges travel both directionsthrough the conductor
In DC - charges move continuously throughout the current in the same direction
