conduction forward voltage is the voltage produced when a diode is connected in forward bias and potential is given across it . when a potential is given across a diode which is connected in forward bias due to repulsion force experinced by the majority charge carriers in p and n type the depletion region gets shrunkn very easily and thus conducton takes place due to the mobility of the charge carriers
What else can I help you with?
Is vacuum tube a voltage controlled device?
yes, effectively a voltage controlled conductance. (conductance being the reciprocal of resistance)
Will you get a electric shock when the negative terminal of the dc power supply is grounded and the positive terminal is held by us?
Only if we are also in contact, directly or indirectly, with ground. By ohm's law, current is voltage divided by resistance. Conductance is the inverse of resistance, so current is voltage times conductance. No conductance - no current.
When the resistance is known as conductance?
Conductance is the reciprocal of resistance, representing how easily electric current can flow through a material. It is defined as the ratio of current (I) to voltage (V) and is measured in siemens (S). A higher conductance indicates lower resistance, meaning the material allows more current to pass through for a given voltage. Thus, when discussing conductance, one is effectively looking at the ease of current flow in relation to resistance.
Using ohm's law express conductance in terms of current and voltage?
Conductance (G) is the reciprocal of resistance (R), expressed as G = 1/R. According to Ohm's Law, resistance is equal to voltage (V) divided by current (I), so R = V/I. Therefore, conductance can be expressed as G = I/V.
What is reciprocal of resistance with unit?
The reciprocal of resistance is called conductance, which measures how easily electric current can flow through a material. The unit of conductance is the siemens (S), which is equivalent to inverse ohms (1/Ω). Conductance is defined as the ratio of electric current to voltage (G = I/V).
Can you show me how to solve for conductance in a dc circuit please show example?
The conductance between any two points in any DC circuit is(current between the two points)/(voltage between the two points) .
What is the derivative of current with respect to voltage in an electrical circuit?
The derivative of current with respect to voltage in an electrical circuit is called conductance, which represents how easily current flows through the circuit in response to changes in voltage.
What is mutual conductance of triode?
Mutual conductance, often denoted as ( g_m ), is a key parameter in triodes that measures the change in the plate current (( I_p )) relative to the change in the grid voltage (( V_g )), while keeping other voltages constant. It is defined as ( g_m = \frac{dI_p}{dV_g} ). This parameter indicates the amplification capability of the triode; a higher mutual conductance signifies greater sensitivity of the plate current to variations in the grid voltage, resulting in increased amplification. Mutual conductance is typically expressed in units of siemens (S).
What is mutual conductance of fet?
Mutual conductance, often denoted as ( g_m ), is a key parameter in field-effect transistors (FETs) that measures the change in the drain current in response to a change in gate voltage while keeping the drain-source voltage constant. It essentially reflects the transistor's sensitivity to gate voltage variations, indicating how effectively the gate controls the flow of current between the source and drain. A higher mutual conductance value indicates greater amplification capability and better performance of the FET in amplifying signals.
What is the voltage gain of the FET amplifier?
It can be answered in two ways : 1. ratio of output & input voltages [Vout / Vin] i.e Drain voltage(Vds)/Source voltage(Vs). 2. multiplication of trans-conductance & drain resistance .
Using Ohm's Law explain how voltage changes in relation to current assuming that resistance remains constant?
how do you use ohms law express conductance in terms of current and voltage?
What is the difference between specific conductance and equivalence conductance?
Specific conductance is the conductance of a specified length of a substance, typically 1 cm, while equivalence conductance is the conductance of all ions produced by one mole of an electrolyte in solution. Specific conductance is a property of the substance itself, whereas equivalence conductance is a property of the electrolyte in solution.
