Q. What is thermal runaway.
The problem of self heating arises due to dissipation of power at the collector junction. The leakage current ICBO is extremely temperature dependent and increase with the rise of temperature of collector base junction. An increase in ICBO causes an increase in collector current IC considerabely. With the increase in collector current ,collector power dissipation increase which raises the junction temperature which leads to further increase in collector current. The process is cumulative and may lead to the eventual destruction of the transistor . This phenomenon is called thermal runaway.
What is a vector impedance meter? State its application.
In a 3-stage continuous ultrafiltration process, a solution is concentrated from 5 gm/Liter to 50 gm/Liter of protein. The final retentate is to have a flow rate of 1000 L/hr. The

Detection and Handling of Gas Leakage : If you are using a toxic gas or have a store for it you must have some devices to indicate the leakage, if any. Though numerous monitoring
Q. Express the waveform of the staircase type shown in Figure as a sum of step functions.
The circuit is altered by replacing the capacitor, C1 with an inductor of 150mH and left with the switch in position (a) for a long time. At time t=0, the switch is moved from posi
