Questions and Answers

What is the total voltage across the battery in a series circuit with voltages of 9V, 3V, and 5V?

18V

20V

15V

17V (correct)

How does current behave in a series circuit?

Current is additive across all components

Current is unique and the same in all components (correct)

Current varies based on each component's resistance

Current flows only through the first component

If the voltage in a series circuit is 17V and the current is 1A, what can you conclude about the circuit?

The circuit has short circuits affecting the current

The circuit has no lamps connected

The circuit operates under a fixed total voltage and current (correct)

The circuit has variable current in each lamp

Study Notes

Series Circuits

Voltage is additive: Total voltage (V_T) = V₁ + V₂ + V₃...
Current is unique: Current (I) is the same in all parts of the circuit. I_T = I₁ = I₂ = I₃...
Example: If V₁ = 2V, V₂ = 3V, and V₃ = 6V, then the total voltage is 11V.
If I_T = 5A, then I₁ = I₂ = I₃ = 5A.
