Question 1

What happens to the current in a series circuit when resistance increases?

  • It increases
  • It decreases
  • It stays the same

πŸ’‘ Hint: Think about Ohm's Law: V = I Γ— R.

Question 2

True or False: In a series circuit, the same current flows through all components.

  • True
  • False

πŸ’‘ Hint: Consider how components are arranged.

Challenge Problems

Push your limits with challenges.

Question 1

In a series circuit with three resistors of values 100 Ξ©, 150 Ξ©, and 200 Ξ© connected to a 12 V battery, calculate the total current and individual voltage drops across each resistor.

πŸ’‘ Hint: Apply Ohm's Law for each resistor after calculating total current.

Question 2

Analyze how adding a fourth resistor of 250 Ξ© affects the current when added in series to the previous three. What will be the new total current?

πŸ’‘ Hint: Recalculate total resistance and see its effect on the current!
