A VERY BIG PROBLEM practically all electronics are restricted to voltages no greater 40 50 volts electrostatic can be as much as 5kv to 50 kv but the source impedance is very hi so while the voltage is there current capabilities are not a low impedance device can possibly survive these discharges but a hi impedance device like MOS cannot survive since the negligent current will raise the potential very hi blowing the device.

Electrostatic discharge is commonly known as?
i think its static electricity.
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. 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."

What damage it does to transistor operation?
Transistor failure can occur due to a variety of reason. The following are some of them. Age Aging of transistor due to temperature variations inside the components due to carrying current can cause failure. The electrical properties of the materials inside can drift due to age. External Causes External causes such as spikes in the power supply, heat, mechanical damage can also result in transistor failures. Hence, all transistors should be adequately protected against overvoltage. Poor Circuit design. Improperly chosen components and wrong circuit design can also result in transistor failure. Hence, all components in the circuit should be properly rated with sufficient allowance for overloading and temperature rise. The failure of one component can lead to cascade failures of other components. Overheating Overheating is the most common cause of transistor failure. Hence, it is important that transistors be provided with cooling mechanism. Devices which contain temperature-sensitive electronic components should be kept in air conditioned environments. Electrostatic Discharge Electrostatic discharge can also damage transistors. Hence proper precautions against Electrostatic Discharge Should be taken.
What is capable of storing electrical energy in an electrostatic field?
condenser
When does damaging electrostatic discharge is most likely to occur?
The humidity is low
What are the different types of electrostatic discharge?
There are many different types of electrostatic discharge. Some examples include electric sparks such as from lightning, corona discharge, and brush discharge.
Which describes static electricity?
Electrostatic discharge
What protects a computer from electrostatic discharge?
A transistor
How does lighting discharge?
When there is a sufficiently strong electrostatic charge, it can cause air molecules to ionize, which are then electrically conductive and create a pathway for the discharge of the electrostatic charge.
Is the static discharge a flow of electrons?
Static discharge is the spark associated with static electricity that is caused by electrostatic discharge.
Electrostatic discharge is commonly known as what?
static electricity
What can be used to prevent electrostatic discharge?
grounding strap
What is a scary electrostatic discharge?
That might refer to a lightning.
What do you call a scary electrostatic discharge?
Frightening lightning
What do you call a very electrostatic Discharge?
Frightening Lightning
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.
