Biology Most workers in nanotechnology are actively monitored for excess static charge buildup. The human body acts like an insulator as one walks across a carpet, collecting $-50 \mathrm{nC}$ per step. (a) What charge buildup will a worker in a manufacturing plant accumulate if she walks 25 steps? (b) How many electrons are present in that amount of charge? (c) If a delicate manufacturing process can be damaged by an electrical discharge of greater than $10^{12}$ electrons, what is the maximum number of steps that any worker should be allowed to take before touching the components?

Key Concepts

Charge Quantization

Charge quantization is the principle that electric charge exists in discrete packets, each equal to the charge of an electron or proton. This concept is crucial when calculating the number of electrons corresponding to a given total charge, ensuring that the results align with the fundamental properties of matter.

Electron Charge

The electron charge is the basic unit of electric charge, signifying the quantized nature of charge. It represents the smallest discrete amount of charge that can exist, and all macroscopic amounts of charge are multiples of this elementary charge.

Electrostatic Discharge (ESD) in Manufacturing

Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects, which can be particularly harmful in sensitive manufacturing environments such as nanotechnology. Controlling the accumulation of static charge is vital to prevent ESD events that could damage equipment or components.

Static Electricity

Static electricity refers to the buildup of charge on the surface of objects, often due to friction. This phenomenon is particularly important in environments with delicate electronic or nanotechnological components, as even small amounts of charge accumulation can lead to damaging discharges.

Electric Charge

Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. It is measured in coulombs, and in practical calculations, understanding charge helps in determining the forces and discharges involved in various processes.
