Unformatted text preview: Objective: To study charging and discharging of (I) a single capacitor manually , (II) two capacitors in series using a computer , and (III) a single capacitor using oscilloscope . Step # 1 to 4 in Lab manual at pages 85 to 86. Key is in discharging position 1 kΩ resistor 10 MΩ resistor Volt meter to measure volts Capacitor with capacitance “C” Stop watch to measure time Time T in sec Voltage V in volts Semi-log paper Find Slope= ? ? − ? ? ¡ ? − ¡ ? =? ¢?£ = ¡ ¤ . ??? We know from theory, We get slope from above graph, and we calculate = ? ! Then, =? Time (T) in sec. Voltage in Volts 0 ? 20 ? 40 ? --- ---- - - Following above when you get the value of time constant , then put the value in the following equation-1 to get equivalent capacitance ¡ ¢£ ¤[¥¦§¨§© ª « ¬­ = ª « ® ª « ] for series combination of two capacitors with the capacitance C each....
