Circuits

Front

What is a circuit?

Back

A circuit is a closed loop of conductors through which an electrical current can flow.

Front

What happens in a series circuit when one bulb is broken?

Back

The circuit will no longer allow electrons to flow since there is only 1 path.

Front

What is Ohm's Law?

Back

Ohm's Law states that V = IR, where V is voltage, I is current, and R is resistance.

Front

What is a resistor?

Back

A resistor is a device that provides a constant resistance to the flow of electric current.

Front

What is the effect of removing one bulb in a parallel circuit?

Back

The other bulbs will stay on since this is a parallel circuit.

Front

What is the unit of electrical power?

Back

The unit of electrical power is the Watt (W).

Front

How do you calculate power in a circuit?

Back

Power (P) is calculated using the formula P = IV, where I is current and V is voltage.

Front

What is the role of a fuse in a circuit?

Back

A fuse protects the circuit by breaking the connection if the current exceeds a certain level.

Front

What is the relationship between voltage, current, and resistance?

Back

Voltage is directly proportional to current and resistance, as described by Ohm's Law.

Front

What happens to the total resistance in a series circuit?

Back

The total resistance in a series circuit is the sum of all individual resistances.
