A) 54.6 s B) 564 ms C) 0.564 ms D) 5.64 24) Electrolytic capacitors differ from many other capacitors in construction in that they are: A) smaller. B) sensitized larger. 25) What is the capacitance of a con D) polarized.

Answer 1

Boy If Capacitors connected in parallel then CT = c +2 +63 +C4 +- - -- +ca CT = 0.022 +0.022 +0.022 + 0.022 CT = 0.088 @ 2 Time Time constant for RC circuit =Rc = 47x106 x 120 x103 = 5.64 sec @ :. Time constant =5.64 See e Electrolytic Capacitors differ from many other capacitors in construction in that they are targe polarized" since Voltage on the poritive terminal must be always larger than voltage on negative terminal and also it has high concentration of long. @
