• question_answer1) A working transistor with its three legs marked P, Q and R is tested using a multimeter. No conduction is found between P and Q. By connecting the common (negative) terminal of the multimeter to R and the other (positive) terminal to P or Q, some resistance is seen on the multimeter. Which of the following is true for the transistor?       AIEEE  Solved  Paper-2007

• question_answer2) A parallel plate capacitor with air between the plates has a capacitance of 9 pF. The separation between its plates is 'd'. The space between the plates is now filled with two dielectrics. One of the dielectric has dielectric constant \[{{\kappa }_{1}}=3\] and thickness \[\frac{d}{3}\] while the other one has dielectric constant \[{{\kappa }_{2}}=6\] and thickness \[\frac{2d}{3}\]. Capacitance of the capacitor is now       AIEEE  Solved  Paper-2007
