1

What are Fuses?

Used to break if too much current flows through the circuit.

New cards
2

What are ammeters?

are used to measure current, connected in a series circuits.

New cards
3

What is Potential difference?

is equal to current multiples by resistance- V= IR.

New cards
4

What are Diodes?

They only allow current to flow in one direction which is why they only show a current when potential difference is positive.

New cards
5

What is a Battery

Made up of 2 or more cells, act in the same way as a cells, a filament lamp is a small light bulb.

New cards
6

What is a circuit

Closed loop with a power source and something for electrons to flow through.

New cards
7

What is Resistance?

Everything that resists or opposes the flow of electrons, measured in Ohms (?)

New cards
8

What are Voltmeters?

Used to measure potential difference, connected in parallel circuits.

New cards
9

What are Cells

Used to provide electric power.

New cards
10

How is flow of electricity controlled?

Switches

New cards
11

What are Filament Lamps?

Lamps that contain filament that heat up until it so hot that it emits light, which increases the resistance.

New cards
12

What are Light Emmitting Diodes?

Emit light when current flows through in a forward direction.

New cards
13

What is Potential Difference?

The force driving the flow of electrons, provided by cell /battery measured in Volts (V)

New cards
14

How is a Cell drawn?

Long line is the positive terminal, short line is the negative terminal.

New cards
15

What is the conventional current?

Electrons travel from Negative to positive terminal, however scientist originally thought it went from positive to negative

New cards
16

What is Q=It?

Charge equals current multipled by time
