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

Series Circuit Voltage

The total voltage in a series circuit is the sum of the voltages across each component.

Series Circuit Current

The current is the same throughout all components in a series circuit.

Calculating Series Voltage

Add the voltage drops across each component to find the total voltage.

Calculating Series Current

The current flowing through any component in a series circuit is the same as the total current.

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.
