A Resistor with a Resistance Of $360 \Omega$ Is in a Series Circuit with a Capacitor of Capacitance

question 194

Short Answer

A resistor with a resistance of $360 \Omega$ is in a series circuit with a capacitor of capacitance $7.3$ $\times 10 ^ { - 6 } \mathrm {~F}$ . What capacitance must be placed in parallel with the original capacitance to change the capacitive time constant of the combination to three times its original value?
