Question
Please explain!
In the circuit shown above left, flashbulb A is lighted when the circuit is closed. If a second identical flashbulb B were placed in series with A, the current at point 1 would A. Increase B. Decrease C. Stay the same Answer using the following format: First, pick the best response, and then write a brief justification. For example, "D. This is true because..."

2) Decrease
On adding another bulb in series, resistance increases, thus current = V/R reduces, thus current decreases.
3) Stay same
The voltage across A is constant and resistance of A as well, thus I = V/R stays same
