Most components are designed and built to work at very low voltage. ESD can be of a magnitude of 1000 times greater. So if this voltage can find its way into a circuit it can permanently damage the circuit or worst yet weaken it for a premature failure

What are the factors that affect impedance?
In AC, impedance (Z) takes on real and imaginary components, and so do voltage (V) and current (I). Re(Z) is affected the DC resistance. Im(Z) is determined by the capacitive and inductive components of the circuit.
Individual components in a parallel circuit experience the same?
Voltage
Why is ESD important in the manufacture of circuit boards?
If you do not take ESD precautions when working on a circuit board, or when working with electronic components or assemblies, there is a chance that static charge on your hands or on other places could discharge through one of the components and damage it. Damaging a component means the circuit or assembly or component no longer works correctly, or even worse, will operate normally but will experience a reduced lifetime, ie, fail in the near future.
What is voltage drop in an electrical circuit?
When a current flow on a conductor , or load or resistor, some voltage will drop across that load or resistor.AnswerA voltage drop is the potential difference appearing across individual components in a circuit, necessary to drive current through those components. The sum of the individual voltage drops around a series circuit will equal the supply voltage applied to that circuit.
What is total voltage in a series circuits?
In a series circuit the total voltage is the sum of the voltage drops across all the component in series. When the voltage drops across each the individual components are added up, they will equal the supply (or applied) voltage.
What is the voltage range in which ESD can affect computer components?
Don't know the range but it only takes 10v to fry components. You won't feel see or hear that low of a discharge even.
ESD is least likely to cause damage to which components?
esd damage your computer key board and mouse
Is ESD damage to components readily visible?
Yes
How does aviation deal with ESD?
An electrostatic-sensitive device (ESD) is any component that can be damaged by common static charges which build up on people, tools, and other non-conductors or semiconductors. Often an ESD-safe foam or ESD-safe bag are required for transporting such components.

What are the effects of ESD on computers?
ESD or electro static discharge is harmful to electronic components because it can cause component overload similar to an electric shock
Why take ESD precautions before working in a computer system box?
To not damage the computer components.
What is a myth regarding electro static discharge?
if you can't feel ESD, the surge is not sufficient to harm components.
What is the minimum voltage of an electronic discharge ESD tha you can feel?
3000 volts From ESD Association ESD Handbook ESD TR20.20 section 5.3.2.1: "When people are charged with static electricity, they can release stored energy to conductive objects such as doorknobs and electronic circuits. This transfer of energy is called an electrostatic discharge. Sometimes the electrostatic discharge causes visible sparks, but more often, it is both unseen and unfelt. Electrostatic discharges can damage ESD sensitive components used in modern electronics. Static electricity is a natural phenomenon that occurs in all climates and at all levels of relative humidity year round. Most people cannot feel an electrostatic discharge unless the static voltage is greater than 2000 volts. However, some electronic circuitry can be damaged by ESD that is less than 2000 volts. The damage can be done without people having any sensation of the ESD event. When a wrist strap is worn properly and connected to ground, the person wearing it will stay near ground potential."
How does humidity affect ESD?
Esd is known as electrostatic discharge. Humidity plays a role in electrostatic discharge because it makes it harder for an object to hold an electric charge.
What problems do computer builders have when building a computer so that they can follow instructions?
There are several problems: form factor, power requirements, and ESD. Form factor will affect how the parts will fit into the case and also airflow to facilitate heat exhaust. Power requirements will affect what types of components you can obtain and how much heat will be generated. ESD will ruin exposed electronics, and this will affect how the assembly will work - if working carelessly, one can destroy hundreds of dollars' worth of equipment in one second.
What is the minimum voltage of an electrostatic discharge ESD that you can feel?
1500v From ESD Association ESD Handbook ESD TR20.20 section 5.3.2.1: "When people are charged with static electricity, they can release stored energy to conductive objects such as doorknobs and electronic circuits.
