Critical Rate of Rise of Current
The maximum rate of increase of current during on state which the SCR can tolerate is called the critical rate of rise of current for the device. This is specified at maximum junction temperature. During initial period of turning on only a small area near the gate conducts the anode current. If the current increase too fast localized overheating may take place. This is called the hole storage effect. Due to localized heating the device may get permanently damaged. To day devices are available which can withstand rate o fries of current damaged. Up to 200- 250 a microsecond however in application this rate is hardly allowed to exceed beyond 5-10 a micro second. Protection against di/ dt is provided by series inductor.

Q. What do you mean by Most and least significant digits? The MSD (most significant digit) in a number is the digit which represents the largest part of the number. Therefore i
what part the transistor plays in the circuit
Can add vectors using the parallelogram rule Can multiply a vector by a scalar - result is a parallel vector • length is scaled
cache size, blocks ?
i need a counter of following o/p truth table 00000000 10000000 11000000 11100000 11110000 11111000 11111100 11111110 11111111 00000000 10000000 . . . so please suggest me some IC
By means of nodal analysis, find the current delivered by the 10-V source and the voltage across the 10- resistance in the circuit shown in figure.
trigger capabilities of logic analyser that differentiate it from other devices???
LDAX Load Accumulator Indirect Instruction This instruction is used to copy data from memory location pointed by register pair only BC or DE to the accumulator HL pair
Q. An RL series circuit carries a current of 0.02 cos 5000t A. For R = 100 and L = 20 mH, find the impedance of the series combination and determine the voltage across the series
