Understanding Series and Parallel Circuits

In a series circuit, how does the total voltage relate to the individual voltage drops across each resistor?

• Total voltage is the product of individual voltage drops.

• Total voltage is the difference between the highest and lowest voltage drops.

• Total voltage is the average of individual voltage drops.

• Total voltage is the sum of individual voltage drops.

What remains constant throughout a series circuit?

• Current

• Resistance

• Voltage

• Power

In a parallel circuit, what happens to the current?

• It increases with each path.

• It divides among the paths.

• It decreases with each path.

• It remains constant.

What remains constant across each resistor in a parallel circuit?

• Voltage

• Current

• Power

• Resistance

How is the equivalent resistance calculated in a series circuit?

• By adding the individual resistances.

• By multiplying the individual resistances.

• By subtracting the smallest resistance from the largest.

• By adding the reciprocals of individual resistances.

In a parallel circuit, how is the equivalent resistance determined?

• By subtracting the smallest resistance from the largest.

• By adding the individual resistances.

• By multiplying the individual resistances.

• By adding the reciprocals of individual resistances.

What is the equivalent resistance of two resistors, 6 ohms and 12 ohms, connected in parallel?

• 9 ohms

• 2 ohms

• 4 ohms

• 18 ohms

In a mixed series and parallel circuit, what is the first step in finding the total equivalent resistance?

• Find the equivalent resistance of parallel components.

• Subtract the smallest resistance from the largest.

• Calculate the total current.

• Add all resistances together.

What is the total equivalent resistance of a circuit with resistors of 2 ohms, 4 ohms, and 6 ohms connected in series?

• 12 ohms

• 4 ohms

• 6 ohms

• 8 ohms

What is a key takeaway about resistance in parallel circuits?

• Total resistance is always less than the smallest individual resistance.

• Total resistance is always more than the largest individual resistance.

• Total resistance is equal to the sum of all resistances.

• Total resistance is the average of all resistances.
