Which of the following statements below is not true of a cap

Which of the following statements below is not true of a capacitor? A capacitor is a passive device that follows the passive sign convention Energy stored in a capacitor is directly proportional to the square of the current flow thru the capacitor Voltage across a capacitor = c (dv/dt) Capacitance is measured in Farads All of the above statements are true Which of the following statements is not true about an ideal Op Amp: The Gain (A) = V_0/V_1 i_p = i_n = 0: the current at both the (+) and (-) terminals of an ideal op amp is zero vp = vn: the voltage at both the (+) and (-) terminals of an ideal op amp are the same value vp = vn: the voltage at both the (+) and (-) terminals of an ideal op amp are equal and may not be equal to zero All of the statements above are true

Solution

7) B E = 1/2 cv^2

8) D
