Electricity

What is the flow of charged particles, usually electrons, in conductors like metals?

Electric current.

What is used to measure potential difference?

Voltage (V).

What does 'Amps' refer to in an electric circuit?

The amount of electricity flowing through a circuit.

What does resistance refer to in an electric circuit?

Opposition to the voltage that slows down electricity.

What law states the relationship between current, voltage, and resistance?

Ohm's Law.

What is the formula for Ohm's Law?

$V = I \times R$.

What are the essential components of an electric circuit?

Power source, conductors, load, and switch.

In which direction does conventional current flow?

From positive to negative terminal.

How are components arranged in a series circuit?

End-to-end.

What happens to total resistance in a series circuit with additional loads?

Total resistance increases.

What does a battery symbolize in circuit diagrams?

A pair of long and short parallel lines.

How should an ammeter be connected to measure current?

In series with the load.

What is the unit of resistance?

Ohms (Ω).

What instrument is used to measure voltage?

Voltmeter.

How is resistance affected by the length of the wire?

Resistance increases with wire length.

What is one hazard to consider in electrical experiments?

Electrical shock.

What can be done to prevent short circuits in experiments?

Check connections to prevent unintended current paths.

What effect does temperature have on the resistance of metals?

Higher temperatures generally increase resistance.
