P4.5 Series circuits

Question 1

What is the definition of a series circuit?

Answer 1

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so that the current flows through each component sequentially.

Question 2

True or False: In a series circuit, the total resistance is the sum of the individual resistances.

Answer 2

True

Question 3

Fill in the blank: In a series circuit, the _________ is the same through all components.

Answer 3

current

Question 4

What happens to the total voltage in a series circuit?

Answer 4

The total voltage is the sum of the voltages across each component.

Question 5

Which of the following is true about series circuits? A) They are more complex than parallel circuits B) If one component fails, the entire circuit fails C) They are always safer than parallel circuits.

Answer 5

B) If one component fails, the entire circuit fails.

Question 6

What is the formula to calculate total resistance (R_total) in a series circuit with resistors R1, R2, and R3?

Answer 6

R_total = R1 + R2 + R3

Question 7

In a series circuit with a 12V battery and three resistors of 2Ω, 3Ω, and 5Ω, what is the total current flowing through the circuit?

Answer 7

The total resistance is 10Ω, so the current is 1.2A (using Ohm’s Law: I = V/R).

Question 8

True or False: In a series circuit, the voltage drop across each resistor can be different.

Answer 8

True

Question 9

What is one advantage of using series circuits?

Answer 9

One advantage is that they are simple to design and implement.

Question 10

Multiple choice: What happens to the total current if additional resistors are added in series? A) It increases B) It decreases C) It remains the same.

Answer 10

B) It decreases
