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. A capacitor is a passive device that following the passive sign convention B. Energy stored in a capacitor is directly proportional to the square of the current flow thru the capacitor C. Voltage across a capacitor = C(dv/dt) D. Capacitance is measured in Farads E. All of the above statements are true 8. Which of the following statements is not true about an ideal Op Amp: A. The Gain (A) = V_o/V_i B. i_p=i_n = 0: the current at both the (+) and (-) terminals of an ideal op amp is zero C. vp=vn: the voltage at both the (+) and (-) terminals of an ideal op amp are the same value D. vp=vn: The voltage at both the (+) and (-) terminals of an ideal op amp equal and may not be equal to zero E. All of the statements above are true

Solution

7. correct option is C

voltage across capacitor is given by the formula V= 1/C integral ( i ) dt

8. all of the statements above are true
