TESTE DEIN WISSEN
What is a circuit?
Lösung anzeigen
TESTE DEIN WISSEN
A path that controls the flow of electricity, usually made up of metal wires (sometimes gas, fluids, or other substances)

Includes a power source (provides electrons), a conductor (moves electrons), a load (transforms electrical energy), and a switch (control, absence of a switch means the circuit always runs and the power source drains faster)

TESTE DEIN WISSEN
What is resistance?
Lösung anzeigen
TESTE DEIN WISSEN
Measures how easily electrons flow through a circuit. It is lowest when temperatures are cold.

Measured in ohms (Ω)

Symbol is "R"

R = V / R

TESTE DEIN WISSEN
What is a series circuit?
Lösung anzeigen
TESTE DEIN WISSEN
A circuit of only one pathway in which the current passes through each bulb in turn.

Adding components increases the total resistance.

Adding an extra bulb makes all of the other bulbs dimmer.

TESTE DEIN WISSEN
What is a voltmeter?
Lösung anzeigen
TESTE DEIN WISSEN
Measures the potential difference of voltage between two points.

TESTE DEIN WISSEN
What are insulators?
Lösung anzeigen
TESTE DEIN WISSEN
Electrons are tightly bound to the nucleus of their atoms (resist movement).

Glass and rubber.

TESTE DEIN WISSEN
What is a variable resistor/ rheostat?
Lösung anzeigen
TESTE DEIN WISSEN
A device that gradually changes the flow of current flow in a circuit (for example when you dim the lights).
Lösung ausblenden
TESTE DEIN WISSEN
What is voltage?
Lösung anzeigen
TESTE DEIN WISSEN
How much energy electrons have.

Measured in volts (V).

Symbol for current is "V".

V= I x R.
Lösung ausblenden
TESTE DEIN WISSEN
What is a parallel circuit?
Lösung anzeigen
TESTE DEIN WISSEN
There are separate paths for each section of current.

Adding more pathways with resistance does not effect the total resistance.

Each new load decreases resistance (more pathways)
Lösung ausblenden
TESTE DEIN WISSEN
What are conductors?
Lösung anzeigen
TESTE DEIN WISSEN
Allows current to flow from negative to positive when it is connected to an electrical source.

Metals (copper and iron)

TESTE DEIN WISSEN
What is and ammeter?
Lösung anzeigen
TESTE DEIN WISSEN
Measures the amount of electrons that pass through a point in a circuit each second (current).
Lösung ausblenden
TESTE DEIN WISSEN
What is a resistor?
Lösung anzeigen
TESTE DEIN WISSEN
Limits the amount of current to pass through using resistance.
