Calculate the number of electrons passing through a lamp in one minute, if the current is 100 mA.

Text Solution

AI Generated Solution

To calculate the number of electrons passing through a lamp in one minute when the current is 100 mA, we can follow these steps: ### Step 1: Understand the relationship between current, charge, and time The current (I) is defined as the charge (Q) flowing through a conductor per unit time (t). This can be expressed with the formula: \[ I = \frac{Q}{t} \] Where: - \( I \) is the current in amperes (A), - \( Q \) is the charge in coulombs (C), ...
