Question 1]. Answer clearly [True or False] no abbreviations Student Panther ID a) Source transformation results in independent sources becoming dependent sources .b) Current through capacitance can not change instantly c) Two different valued voltage sources can be connected in parallel .d) Larger the Common Mode Rejection Ratio [CMRR], smaller is the noise immunity for Op.Amp .e) Ideal Op. Amp has very small open loop input conductance f) Disabled current source is similar to an Open Circuit g) Sudden current change in a capacitance results in very large voltage surge across the capacitance h) Maximum Power Transfer operation gives 100% power efficiency in the system i)12 Volt Car battery is powering car parking lights, giving 8 Amperes of current. How m .b h) is expended in 1 Hour? i)Ans J)In part (i) above, if the battery is rated at 360 Watt-Hours; how many hours the battery charge would last? .Question 2] Sources Vx and Vy are DC type and Vy 240 volts. R1- R2 120 Ohms; R3- R4-R5 60 o IR4, IR5 currents through R1, R2, R3, R4, R5 as shown. Given IR5 through R5 is 2.0 Amps, as shown.

Explanation / Answer

A. False, source transformation converts voltage source into current source and vice versa

B. False, current changes instantly through a capacitor

C. False, they cant be connected in parallel

D. False, larger the CMRR greater is the noise immunity

E. Yes, ideal opamp has infinite input resistance and very small conductance

F. Yes disabled current source is treated as an open circuit

G. The voltage increases slowly.

H. false max power transfer gives 50% efficiency
