Problem 8: A capacitor of capacitance C-10 uF has been charged so that the potential difference between its plates is Vo 380 V. The capacitor is then connected to a resistor of resistance R-6.5 k2. The switch S is closed, and the capacitor begins to discharge Randomized Variables Vo 380 V l- ©theexpertta.com Δ Part (a) Calculate the time constant of the circuit in seconds. tan() cos0) cotanasin) acos(0 atan() acotan sinh() cosh)tanh cotanh) O Degrees O Radians sin HOME 4 5 6 0 BACKSPACE CLEAR Submit Hint I give up!
