Three identical lamps are connected in series with a battery. The ammeter near the battery reads 0.5 A. What is the current between L2 and L3?
Question 1 Report
Three identical lamps are connected in series with a battery. The ammeter near the battery reads 0.5 A.
What is the current between L2 and L3?
Answer Details
In a series circuit, there is only one path for the current to flow through. This means the current is the same at every point in the circuit. The ammeter near the battery reads 0.5 A, so the current flowing through every component, and through every section of wire, is also 0.5 A.
The current between L2 and L3 is therefore 0.5 A, identical to the current measured at the ammeter. The current does not split, divide, or reduce as it passes through successive lamps in a series arrangement. Each lamp may have a voltage drop across it, but the current remains constant throughout. This is a direct consequence of conservation of charge: charge cannot accumulate at any point in the circuit, so the same amount of charge per second must pass through every cross-section of the series loop.
