Circuits

Front

What do motors create?

Back

Mechanical energy.

Front

What type of circuit allows multiple paths for current to flow?

Back

Parallel circuit.

Front

Is it safe to plug too many devices into one outlet?

Back

No, it can overload the circuit.

Front

What is the principle of solar photovoltaics?

Back

Electron-hole pair production.

Front

What happens to current as resistance increases in a circuit?

Back

The current decreases.

Front

What is a series circuit?

Back

A circuit where components are connected end-to-end, so current flows through each component in turn.

Front

What is Ohm's Law?

Back

Voltage = Current x Resistance.

Front

What is the unit of electrical resistance?

Back

Ohm (Ω).

Front

What is a short circuit?

Back

An unintended path in a circuit that allows current to flow with little or no resistance.

Front

What is the function of a fuse in a circuit?

Back

To protect the circuit by breaking the connection if the current is too high.
