(16 cards)
electrical conductor
Material that transfer electric current through them
Anziehung
attraction
Abstoßung
repulsion
insulator
material that does not allow current to flow through not
electric circuit
path for transmitting current
ac
alternating current
dc
direct current
definition current
current is the rate of flow of charge
what is the smallest unit of charge
the charge of an electron
definition potential difference
work done per unit charge
definition work
energy transferred when moving the charge
what does an electric circuit consist of at least
- device that gives energy to charged particles
- device that uses current
- connecting wires
What does resistance depend on?
area
length
resistivity
thermistors
components whose resistance is dependent on temperature
LDR
light dependent resistors
transformers
devices that alter voltage and current
Electric current flows through primary coil
- -> magnetic current created
- -> current in secondary coil induced
