When an Initially Uncharged Capacitor Is Charged Through A $25 - \mathrm { k } \Omega$

question 52

Short Answer

When an initially uncharged capacitor is charged through a $25 - \mathrm { k } \Omega$ resistor by a $75 - \mathrm { V } \mathrm { dc }$ ideal power source, it takes $0.23 \mathrm {~ms}$ for the capacitor to reach $50 \%$ of its maximum charge? What is the capacitance of this capacitor?
