cells

17
Q

Circuit

A

continuous pathway along which electrons can move

18
Q

Load

A

a light or motor

19
Q

closed circuit

A

a complete loop in which electrons are able to move from the negative to positive terminals

20
Q

open circuit

A

a circuit that stops the flow of electricity by having a gap

21
Q

electrodes

A

are conductors that allow electrons to leave and enter the cell

22
Q

electrolyte

A

a solution that contains free charged particles that are necessary to carry one electrode from another

23
Q

what is an example of an electrolyte

A

a potato or gatorade

24
Q

magnetic field

A

when an electric current flows through a wire, it produces a magnetic field around the wire

25
Q

fuse

A

prevents wire from becoming overheated

26
Q

short circuit

A

occurs when there is no load to provide resistance. The electrons will rush out of the battery and cause the wires to heat up
