Electricity Flashcards
What is electricity
electricity is a form of energy
what is electric current
the flow of charged particles
what is electrical circuit
the path in electricity flows
what is a semi conductor
non metals that are able to conduct some amount of energy
what are electrons
charged particles that flow as a electric current in a solid
unit, symbol, instrument used for current, voltage, resistance
current - amps , A, ammeter
voltage- volts, V, voltmeter
Resistance- ohms
5 components of an electrical circuit
ammeter
voltmeter
resistors
switch
fuse
what is current
the flow of charged particles
what is voltage
provides energy for electrons to flow`
resistance
hinders the flow of electrons
what are the 2 ways circuits can be connected
series and parallel
what is a series circuit
when components in a circuit is connected one after another
what will happen if there is a break in a series circuit
no current flow through the other components
what is parallel circuit
when the components are collected in parallel there is more than one route that the current can take to move around the circuits
what will happen if there is a break in a parallel circuit
current can still flow in other parallel parts of the circuit
why is parallel circuits more useful than series circuit
bc switching off one one appliance does not mean switching off all the others
what is electromotive(emf)
the source gives electrical energy each electron moving in a circuit
unit of emf
volt
what is an electrical energy difference called
potential difference
