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.
Various FET biasing circuits are as follows: 1. Fixed bias 2. Self bias 3. Potential divider bias 4. Current-Source bias
No, overcharging cellphone will not cause an electrical short circuit.
An electric circuit.
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.
series circuit
emitter bias provides a feedback to the circuit so that circuit remains in linear regionn
of course stability of self bias circuit is much greater than fixed bias circuit

Not sure what you mean with "lemon circuit", but in an electrical circuit, the switch can be just about anywhere.
The emitter bias circuit is called self-bias because the bias voltage across the emitter-resistor is based on the transistor's own characteristics. The bias voltage adjusts itself based on the varying collector current to stabilize the operating point of the transistor. It is a self-adjusting mechanism that helps maintain a stable bias point for the transistor.

Water always flow from height to bottom mean high potential level to low potential level same happens in electrical circuit.
Short circuit is when two phases or lines on the power circuit has be abruptly bridged, causing a protected electrical circuit to trip.
No, cathodes are negative in an electrical circuit.
The current flowing in an electrical circuit.
The drawing of an electrical circuit is called a.............= schematic drawing.
If you mean a bare copper wire, that is the "ground" wire.
