what are electrical circuits?
pathways for electric current/charge to flow through
what is an electrical current?
flow of electric charge through a conductor
what is an electrical circuit
a continuosly conducting path along which electric current can flow
name the basic components of a circuit
conducting wire switch cell/battery resistor
what is the function of a conductor?
material for electrons to flow through made of good conductors such as metal carry electricity over short or long distances
what is the function of a switch?
breaks the flow of electric charge in the conductors when open, circuit = broken, no current will flow through when closed, circuit = complete, current will flow through convenient way of controlling electricala flow in currents
what is the function of a resistor
oppose the flow of current copper wire offer some resistance and become hot when charge flows through them resistors affect amount of current in a circuit
give an example of a resistor
lightbulb: contains resisted wire called a filament (tungsten) filament resists flow of charge filament heats up to be white hot, gives of light and heat resistant wire connected to : • metal casing of bulb • solder knob
name the effects of an electric current
a. heating effect b. chemical effect c. magnetic effect
what is an electromagnet?
a current carrying conductor that produces a magnetic field and can be used as a temporary magnet
what is an electromagnet made up of?
a solenoid with a core of magnetic material such as soft iron forms temporary magnet that can be switched on/off by switching current off/on
what is electrolysis?
when an electric current is used to break a chemical substance down into its composite elements
what is an electrolyte?
a solution containing free electrons or fluid that a current can pass
what is an electrode?
small rods connected to a battery or sell
what is an anode
the positive terminal
what is a cathode?
the negative terminal
what is electroplating?
when metals like iron or copper is covered with a layer of silver to make them shiny and prevent them from rusting
( last card no. 18) i’m sorry to interupt you but unfortunateley your provider cannot continue out of fatigue (tiredness) error code : ‘554 5.7.1 please press space or touch ‘‘reveal’’
don’t give up! '’check in your book!!!’’ go on!! look for series and parallel circuits and read from there! thanks for your passionce (if that’s how you spell it…)
