The charging and discharging of the capacitor will be stabilized at this period. The total capacitance for series capacitor (1/ CT = 1/ C1 + 1/ C2) and the transient period 5τ is calculated. (b) Transient Response of RC circuit when capacitors are in seriesĬapacitor in Series 1.RC circuit is constructed by using one R = 100 kΩ and two C = 470 ♟. Step 6 and 7 is being repeated and that value is recorded in Table 4-3. Step 5 is being repeated and that value is recorded in Table 4-3. Step 3 and 4 in the first experiment is being repeated.Ĥ.

The total capacitance for parallel capacitor (CT = C1 + C2) and the transient period 5τ is calculated. The capacitors are put in parallel to each others. RC circuit is constructed by using one R = 100 kΩ and two C = 470 ♟. (b) Transient Response of RC circuit when capacitors are in parallelġ. Items 3 to 6 is repeated with R = 100 kΩ. The jumper wire is put in the discharge position and the capacitor voltage VC is recorded at the same time interval as in step 5. One person is assigned to call off time and the other person is assigned to read and record down the voltage. Then, the switch is left in up position until the voltage VC stabilizes at the maximum value (when the second digit of the multimeter is no longer changing over 30 second period) and that value is recorded in Table 4-2. VC is recorded for every 20 seconds up to 4 minutes (240 seconds). Then the jumper wire is put in the charge position.ĥ. The jumper wire is left in the discharge position until the voltage across the capacitor stabilizes at 0 volt. The negative side of the electrolytic is checked to ensure that it is connect to the ground. A jumper wire is used for the switch to connect the resistor either to the voltage source or to the reference node (ground). The circuit of Figure 4-2 is constructed using the values of R and C given in step 1. This also called as transient period which then recorded in Table 4-1. A capacitor will be mostly charged or discharged after five time constant, 5τ. Time constant τ = RC for a series RC circuit having C = 470 ♟ for R = 68 kΩ and R = 100 kΩ is calculated to gain a perspective of how the transient will take.
