physicssssss Flashcards
force that pushes each charge across the circuit travelling through conductive wires
ELECTORMOTIVE FORCE
electromotive force unit
VOLTS
electromotive force unit denoted as ?
E
the battery iself that supplies or generates electricity
ELECTROMOTIVE FORCE
no current or no external load
ELECTROMOTIVE LOAD
resistance of battery inside
INTERNAL RESISTANCE
internal resistance is represented as/
SMOL r
the potential difference across the terminal of a cell when currwenrt i flowing through it less than when there is no current flowing
INTERNAL RESISTANCE
when battery connected to external load/current floating
INTERNAL RESISTANCE
works when connected to a wire
INTERNAL RESISTANCE
the amount of energy carried by charge between two points in a circuit
POTENTIAL DIFFERENCE
the potential difference across the terminals of the cell when current flows through
TERMINAL VOLTAGE
when an external load is connected to a battery there will be a potential difference
TERMINAL VOLTAGE
electrical energy unit
