A current of is drawn by a filament of an electric bulb. The number of electrons passing through a cross-section of the filament in would be roughly?
Explanation for the correct option A:
Step 1: Given data
Electric current flowing through the filament,
Number of electrons passing through the filament,
Time duration in which the electrons flow through the filament,
Step 2: Formula used
Where, () is the charge on the electron.
Step 3: Calculation of the number of electrons flowing through the filament
Substituting the given values in equation (a), we get
Hence, option (A) is correct.
