Resistors in Series

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

• Add all the resistance values together.

• Subtract the resistance values

• Divide the resistance values

• Multiply the resistance values

If three resistors are connected in series with values of 2 ohms, 4 ohms, and 6 ohms, what is the total resistance?

• 10 ohms

• 8 ohms

• 14 ohms

• 12 ohms

If a 12V battery is connected to a circuit with three resistors in series of 3 ohms, 6 ohms, and 9 ohms, what is the total current flowing through the circuit?

• 0.67 A

• 1.25 A

• 0.5 A

• 2 A

In a circuit with two resistors in series, if the voltage drop across the first resistor is 4V, what is the voltage drop across the second resistor if the total voltage is 12V?

• 8V

• 6V

• 2V

• 10V

• 1A

• 1.5A

• 2A

• 3A

In a series circuit, how is the voltage distributed across the resistors?

• It is the same across each resistor

• It is divided equally across all resistors

• It is divided based on the resistance values

• It increases with each resistor

If the voltage across a series circuit with a single resistor is 10V and the current is 2A, what is the resistance of the resistor?
