Chapter 10, Problem 7RAT
Compared with the amount of current in the filament of a lamp, the amount of current in the connecting wire is
(a) definitely less.
(b) often less.
(c) actually more.
(d) the same.
(e) Incredibly, all of these.
Expert Solution & Answer
To determine
The correct option for the statement “Compared with the amount of current in the filament of a lamp, the amount of current in the connecting wire is”.
Answer to Problem 7RAT
The correct option for the statement “Compared with the amount of current in the filament of a lamp, the amount of current in the connecting wire is” is option (d).
Explanation of Solution
The filament of bulb glows due to the heating effect of electric current supplied by an external source. The current that flows through the connecting wire reaches the filament of bulb and due to heating effect, it produces a sensation of glowing to the surroundings.
The connecting wires and the filament of bulb are connected in series, so the same amount of current reaches the filament of the bulb, but the voltage drop across the connecting wire and the filament of bulb is not same but depends on the resistance values of connecting wires and the filament.
The current flows through the connecting wire and filament of bulb is same, as both are connected in series and the value of the current depends on the resistance offered by both to the flow of electrons.
Conclusion:
Therefore, the correct option for the statement “Compared with the amount of current in the filament of a lamp, the amount of current in the connecting wire is” is option (d).
