Unit 4_Flashcardizz Review Game for Learning Target Quiz #1

Front

What is resistance in an electrical circuit?

Back

Resistance is anything that opposes the flow of electrons and is measured in Ohms (Omega – Ω).

Front

What happens to the brightness of bulbs when a fourth bulb is added in a series circuit?

Back

The bulbs would get dimmer.

Front

What is voltage in an electrical circuit?

Back

Voltage is the potential difference between two points on a circuit and is measured in Volts.

Front

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

Back

The overall voltage increases.

Front

What is the unit of measurement for current?

Back

Current is measured in Amperes (A).

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). It is expressed as V = I × R.

Front

What does the symbol 'I' represent in electrical circuits?

Back

The symbol 'I' represents current, which is the rate of flow of electric charge.

Front

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

Back

According to Ohm's Law, voltage (V) = current (I) × resistance (R).

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases.

Front

What is the effect of adding resistors in parallel on total resistance?

Back

The total resistance decreases.
