Bias is a permanent voltage, applied to the input of an amplifier device, in order to make it work in the correct area of an amplification curve. Valves (thermionic tubes) and semiconductors (transistors) both use bias in their grid or base connection. A negative swing in the input could put the control input below the working of the device and cause it to switch off. This is undesirable as it will show as distortion. The bias raises the zero point, so that the signal will not turn the device off.

What does the electrical term amperes mean?
Amperes are units of electrical current. They measure the amount of charge passing a point in a circuit line given a set amount of time.
An electrical circuit with components placed one after the other?
series circuit
Why emitter bias circuit is called self bias circuit?
emitter bias provides a feedback to the circuit so that circuit remains in linear regionn
Why emitter bias circuit is called self bias?
emitter bias provides a feedback to the circuit so that circuit remains in linear regionn
Which stability is greater between self bias and fixed bias?
of course stability of self bias circuit is much greater than fixed bias circuit

Where can i place the switch in the lemon circuit?
Not sure what you mean with "lemon circuit", but in an electrical circuit, the switch can be just about anywhere.
What is mean by GOD in electrical circuit?

In which ways is a water circuit similar to an electrical circuit?
Water always flow from height to bottom mean high potential level to low potential level same happens in electrical circuit.
When you turn on a television what is the electrical circuit?
The electrical circuit when turned on it is considered closed. By the same token when an electrical circuit is turned off the electrical circuit is considered open.
What things need a electrical circuit?
Electrical devices need an electrical circuit.
Where does energy leave a circuit?
I assume you mean electricity not energy. The electrical energy doesn't leave the circuit as such it is converted by a component. E.G. A bulb in a circuit will convert the electrical energy into light and some heat.
What does voltage mean in science?
It is defined as electromotive force, and the difference in electrical potential between 2 points in a circuit. It has also been explained as the pressure in an electrical circuit.
