Circuits review

Front

What is the same value throughout a parallel circuit?

Back

Voltage is the same across all components in a parallel circuit.

Front

What happens to the brightness of bulbs when an additional bulb is added in series?

Back

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

Front

What is the relationship between voltage, current, and resistance in a circuit?

Back

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

Front

In a parallel circuit, how does the total current relate to the individual currents?

Back

The total current is the sum of the individual currents through each parallel branch.

Front

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

Back

Adding more resistors in parallel decreases the total resistance.

Front

What is the unit of electrical current?

Back

The unit of electrical current is the Ampere (A).

Front

What is the unit of electrical resistance?

Back

The unit of electrical resistance is the Ohm (Ω).

Front

What is the unit of electrical voltage?

Back

The unit of electrical voltage is the Volt (V).

Front

How do you calculate the total resistance in a series circuit?

Back

In a series circuit, the total resistance is the sum of all individual resistances: R_total = R1 + R2 + R3 + ...

Front

What is a short circuit?

Back

A short circuit occurs when there is a low-resistance connection between two points in a circuit, causing excessive current flow.
