Resistor Series and Parallel Circuits

What is the main characteristic of resistors in series?

• They have the same current flowing through them.

• They have different currents flowing through them.

• They have the same voltage across them.

• They have different voltages across them.

What does the epsilon symbol next to a battery represent?

• The internal resistance of the battery.

• The current through the battery.

• The electromotive force (EMF) of the battery.

• The power of the battery.

How can the electric potential difference in a series circuit be described?

• It is the difference between the potential differences across each resistor.

• It is the same as the potential difference across one resistor.

• It is the product of the potential differences across each resistor.

• It is the sum of the potential differences across each resistor.

According to Ohm's Law, what is the relationship between electric potential difference, current, and resistance?

• Electric potential difference equals current divided by resistance.

• Electric potential difference equals current times resistance.

• Electric potential difference equals resistance minus current.

• Electric potential difference equals resistance divided by current.

What happens to the equivalent resistance when resistors are added in series?

• It becomes zero.

• It increases.

• It remains the same.

• It decreases.

What is a key feature of resistors in parallel?

• They have the same current flowing through them.

• They have different voltages across them.

• They have the same voltage across them.

• They have different currents flowing through them.

How is the equivalent resistance of two resistors in parallel calculated?

• By multiplying the resistances.

• By taking the inverse of the sum of the inverses of the resistances.

• By subtracting the resistances.

• By adding the resistances.

What does conservation of charge imply in a parallel circuit?

• The current into a junction is more than the current out.

• The current into a junction equals the current out.

• The current into a junction is zero.

• The current into a junction is less than the current out.

What happens to the equivalent resistance when resistors are added in parallel?

• It becomes infinite.

• It decreases.

• It remains the same.

• It increases.

What is the general effect of adding resistors in series versus parallel on equivalent resistance?

• Both series and parallel increase.

• Series decreases, parallel increases.

• Both series and parallel decrease.

• Series increases, parallel decreases.
