Q: In a series circuit, what is the relationship between the current flowing through each component?

The current is the same through all components. — Current remains constant in a series circuit.

Q: How are resistors connected in a series circuit?

End-to-end, forming a single path. — Series connection implies a single path for current.

Q: What happens to the total resistance (Rt) when resistors are connected in series?

Rt = R1 + R2 + R3 + ... — Series resistors add up.

Q: If three 10-ohm resistors are connected in series, what is the total resistance?

30 ohms — R_total = 10+10+10 = 30 ohms.

Q: In a series circuit, if one component breaks (opens), what happens to the circuit?

The entire circuit is broken (no current flows). — A break in series circuit interrupts current flow.

Q: What is the relationship between the source voltage (Vs) and the voltage drops across each component in a series circuit?

Vs = V1 + V2 + V3 + ... — Kirchhoff's Voltage Law applies.

Q: Which of the following is an advantage of a series circuit?

Simple to design. — Series circuits are often easier to set up.

Q: What is the primary disadvantage of a series circuit?

If one component fails, the whole circuit fails. — A single point of failure disables the circuit.

Q: If you add more resistors in series, what happens to the total resistance?

Increases. — Adding resistors in series always increases the total resistance.

Q: Which of the following is *not* a characteristic of a series circuit?

Total resistance is less than the smallest individual resistance. — Total resistance is always higher than individual in a series.

Question 12 of 15

A series circuit consists of a 10V source and two resistors: R1=2 ohms, R2=3 ohms. What is the current?

I = V/R, Rtotal= 5 ohms, I = 10/5 = 2 A

Question 13 of 15

In the previous problem, what is the voltage drop across R1?

V1 = I * R1 = 2A * 2 ohms = 4V

Question 14 of 15

What type of circuit is often used in string lights (Christmas lights)?

Older string lights use series connections.

Question 15 of 15
