Set the switch to ensure the capacitor is fully discharged as above. Start the simulation and move the switch to charge up the capacitor then press-pause when the capacitor is charged. (i) Print-screen/snip your oscilloscope / graph screens and record your results on table1...To do this, record the capacitor voltage and circuit from either your graphs or meter readings at intervals of 0.2s. (ii) To verify your results, calculate the time constant, then using the charging formulae from your notes, find the capacitor voltage and the circuit current-at-time t=0.8 & 1.8s. Show evidence of your calculations and compare these with the measured values found at these specified times from your table1/graphs. Briefly comment on your comparison (iii) Using the simulator graphs (or manually plot the graphs from your table 1 results) for voltage and current, explain and the relationship between-voltage-and-current-in-this switched on circuit Time (s) Vc (Volts) [Measured] I (mA) [Measured] Time (s) Vc (Volts) [Measured] I (mA) [Measured] 0 1.6 .2 1.8 .4 2.0 .6 2.2 .8 2.4 1.0 2.6 1.2 2.8 1.4 3.0 Table 1-Charging-values
