In a 30-second interval, an electric device with a current of 15 amps allows approximately 2.81 x 10^21 electrons to flow through it. This is calculated using the relationship between current, charge, and the charge of an electron. The total charge is determined by multiplying the current with time, and the number of electrons is found by dividing the total charge by the charge of one electron.

Antimicrobial agents target various cellular components in microbes, including the cell wall, cell membrane, nucleic acids, and proteins. Their adverse effects, known as their mode of action, vary based on the specific agent and its mechanism. Selective activity of these agents is crucial for their effectiveness against specific types of microbes. ;
