What is the dynamic resistance of the diode?
Dynamic resistance of a diode, often denoted as ( r_d ), is the small-signal resistance that characterizes the diode's response to small changes in voltage around a specific operating point. It is defined as the derivative of the diode's voltage-current (V-I) characteristic with respect to current, ( r_d = \frac{dV}{dI} ). This resistance is typically much lower than the static resistance of the diode and is influenced by factors such as temperature and the level of forward bias current. In the forward-bias region, dynamic resistance can be approximated as ( r_d \approx \frac{nV_T}{I} ), where ( n ) is the ideality factor, ( V_T ) is the thermal voltage, and ( I ) is the forward current.
What is SAP with respect to SCADA systems?
HI guys I have a question:what is SAP with respect to SCADA system?
Explain the difference between the overhead apportionment and overhead absorption?
If the cost can be tracked towards a cost object, then it is called overhead absorption. If the cost can not be tracked with respect to a specific cost center or cost object, then the entire cost is distributed to all the cost centers, based on the usage ratio. This is called Overhead apportionment. UdhayAnand AVB
What is the difference between wavelet tree and wavelet packets?
Wavelet tree is recursively built applying decomposition and approximation filter only to the (father wavelet) approximation filter output at each step (or level). Wavelt packets, instead, are constructed by applying both filters to approximation and decomposition filter output resulting in a 2^(n+1)+1 nodes with respect to 2(n+1)+1 nodes of standard discrete wavelet tree
What are the two main characteristics of a transistor?
- The ratio of the dc collector current (IC) to the dc base current (IB) is thedc beta (bDC).- bDC is called the gainof a transistor:bDC = IC/IB- Typical values of bDC range from less than 20 to 200 or higher.- bDC is usually designated as an equivalent hybrid (h)parameter:hFE = bDC- The ratio of the collector current (IC) to the dc emitter current (IE) is the dc alpha (aDC). This is a less-used parameter than beta.aDC = IC/IE- Typical values range from 0.95 to 0.99 or greater.- aDC is always less than 1.- This is because IC is always slightly less than IE by the amount of IB.- From graph above we can see that there are 6 important parameters to be considered:i) IB: dc base current.ii) IE: dc emitter current.iii) IC: dc collector current.iv) VBE: dc voltage at base with respect to emitter.v) VCB: dc voltage at collector with respect to base.vi) VCE: dc voltage at collector with respect to emitter.- VBB forward-biases the BE junction.- VCC reverse-biases the BC junction.- When the BE junction is forward biased, it is like a forward biased diode:VBE ? 0.7 V- But it can be as high as 0.9 V (and is dependent on current). We will use 0.7 V from now on.- Emitter is at ground. Thus the voltage across RB isVR(B) = VBB- VBE- AlsoVR(B) = I­RRB- Or:I­RRB = VBB- VBE- Solving:IB = (VBB- VBE)/RB- Voltage at collector with respect to grounded emitter is:VCE = VCC - VR(C)- Since drop across RC is VR(C) = ICRC the voltage at the collector is also:VCE = VCC - ICRC- Where IC = bDCIB. Voltage across the reverse-biased collector-bias junction isVCB = VCE - VBEthank you

Is less than or greater than zero external voltage applied on diode when you deal with forward biased?
A forward-biased diode has a positive DC on its anode with respect to its cathode.
Can you call forward bias voltage as positive voltage?
it is not necessary that always positive voltage should act as a forward bias voltage , it is the potential difference between cathode and anode that makes it forward or reverse biased .it the anode(p- doped material) positive with respect to cathode(n- doped material) --> forward biasedit the anode(p- doped material) negative with respect to cathode(n- doped material) --> reverse biasedex.anode - 5v cathode - 3vanode - 1v cathode - -2vboth the examples are forward biased.
Explain about: How was the question of the existence of God resolved with respect to the notion referring expression?
I need a specific answer.
Why emitter is always forward biased with respect to base?
It is because the emitter is the source of charge carriers and we require to move these charge carriers into base which is obtained only by forward baising the base emitter junction.
To bend the head forward to show respect?
Bending the head forward to show respect is a gesture often associated with humility and acknowledgment of another's presence or authority. This action can signify reverence, submission, or gratitude, depending on the cultural context. It is commonly seen in various traditions and ceremonies, where such non-verbal communication reinforces social hierarchies and values. Overall, it serves as a powerful means of expressing respect without the need for words.
