Unformatted text preview: 31. 32. 33. 34. 35. 36. The two circuits shown below, contain identical fuily charged capacitors at t=0. Circuit 2 has twice as much resistance as circuit 1.What will be the status of charge on the two capacitors a short time after t=0? .’ﬁ (3) __ QPQz _ (b) ' ' Q1<Q2 J (C) Q1=Q2 (d) None of the above What is the value of capacitance of a capacitor in an RC circuit with 1 kHz signal at -3db frequency (the resistor is 1 Kohm}? The width of a compact disc (CD) bit is approximately equal to the wavelength of the green laser: ' True False A change in temperature at the junction of two different metals produced when an electric current ﬂows through them is called Seebeck effect. True False] The gauge factor of a strain gauge is a function of Poisson‘s ratio- True False The Newton's law of cooling states that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings: True .
