Understanding Series Circuits

What is the total voltage in a series circuit with a 12V and a 6V resistor?

• 6V

• 18V

• 12V

• 24V

How does the current behave in a series circuit?

• The current varies at different points in the circuit.

• The current is highest at the beginning of the circuit.

• The current is zero in a series circuit.

• The current is constant throughout the series circuit.

If three resistors of 2Ω, 3Ω, and 5Ω are in series, what is the total resistance?

• 8Ω

• 6Ω

• 10Ω

• 12Ω

What happens to the voltage across each resistor in a series circuit?

• The voltage across each resistor remains constant.

• The voltage is only present across the first resistor.

• The voltage across each resistor is equal regardless of resistance.

• The voltage across each resistor is divided based on its resistance.

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

• Total voltage is the sum of individual voltages in a series circuit.

• Total voltage is the maximum voltage of any component in a series circuit.

• Total voltage is the average of individual voltages in a series circuit.

• Total voltage is the product of individual voltages in a series circuit.

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

• The total resistance fluctuates randomly.

• The total resistance remains the same.

• The total resistance increases.

• The total resistance decreases.

In a series circuit, if one resistor fails, what happens to the circuit?

• The circuit becomes open and stops functioning.

• The circuit increases its resistance.

• The circuit short-circuits and causes a surge.

• The circuit continues to function normally.

How do you find the equivalent resistance of resistors in series?

• R_eq = R1 / R2 / R3

• R_eq = R1 + R2 + R3

• R_eq = R1 - R2 - R3

• R_eq = R1 * R2 * R3
