Unit 4_Flashcardizz Review Game for Learning Target Quiz #1

Front

What is current in an electrical circuit?

Back

Current is the flow of electric charge, measured in Amperes (A).

Front

What is the direction of electron flow in a circuit?

Back

Electrons flow from the negative terminal to the positive terminal, which is opposite to the conventional current direction.

Front

What happens to the overall voltage when another battery is added in series?

Back

The overall voltage increases because the voltages of the batteries add up.

Front

What effect does adding more bulbs in series have on their brightness?

Back

The bulbs get dimmer because the total resistance increases, reducing the current.

Front

What happens to the other bulbs if one bulb burns out in a series circuit?

Back

The other bulbs go out because the circuit becomes open.

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, preventing current from flowing.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows current to flow.

Front

How does resistance affect current in a circuit?

Back

Increased resistance decreases the current, according to Ohm's Law (I = V/R).

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R).

Front

What is the unit of voltage?

Back

The unit of voltage is the Volt (V).
