Electrical Physics Flashcards
When is an object defined to be charged?
An object is charged when it has an unequal number of protons and neutrons.
What is static energy
Static energy occurs when an object’s charges aren’t moving and electrons aren’t being transferred to one object to another.
What is potential difference?
Potential difference is when there is a seperation between charges creating potential energy difference between them.
Which way does conventional current flow?
Conventional current is the flow of electrons from the positive terminal to the negative terminal.
Which way does electron current flow?
Electron current is the flow of electrons from the negative terminal to the positive terminal.
What is an electric circuit?
An electric circuit is a closed loop in which current can flow continuously.
What is power?
Power is the the rate at which energy is transformed across the circuit.
What is a series circuit?
A series circuit is when 2 or more electrical components are connected one after another on the same conducting pathway. (extra note: Current in a series circuit is constant, volts and resistance can be added up like normal to find total voltage/resistance (e.g. V1+V2+V3+…))
