05. A capacitor, initially charged to Qmax = 11.8 p0 and with a maximum potential difference of 4.5 V was discharged through a resistor. After a time constant of 35 milliseconds (ms), the p.d. across the capacitor was 37% of its initial value of 4.5 V. apps Explain what is meant by capacitance and calculate the capacitance of the capacitor. (4) Calculate the maximum energy that can be stored in the capacitor. (2) Calculate the charge remaining in the capacitor after 70 ms. (3) Calculate the voltage across the capacitor after 70 ms. (3)
