Physics Questions

Given the combination of capacitors C1 = 3.00 μF, C2 = 11.0 μF, C3 = 3.00 μF, and C4 = 5.00 μF, what is the equivalent capacitance CA of the network? Then, with the addition of capacitors C5 = 6.00 μF and C6 = 3.00 μF, what is the equivalent capacitance CB of the new network? Please express both answers in microfarads.

Short Answer

The equivalent capacitance for Figure 1 is approximately 2.09 ¬¨¬µF, while for Figure 2, it’s around 1.73 ¬¨¬µF. The calculations include combining capacitors in parallel and series as per their configurations.

Step-by-Step Solution

Step 1: Calculate Equivalent Capacitance for Figure 1

To find the equivalent capacitance of the capacitors in Figure 1, first calculate the combined capacitance of capacitors C3 and C4 which are in parallel. Use the formula:

  • C34 = C3 + C4 = 3.00 ¬¨¬µF + 5.00 ¬¨¬µF = 8.00 ¬¨¬µF

Next, find the equivalent capacitance of C2 and C34 using the series formula:

  • 1/C234 = 1/C2 + 1/C34
  • C234 = 4.40 ¬¨¬µF (approx.)

Finally, combine C1 and C234 to determine the total capacitance:

  • 1/C_total = 1/C1 + 1/C234
  • C_total = 2.09 ¬¨¬µF (approx.)

Step 2: Calculate Equivalent Capacitance for Figure 2

In Figure 2, find the equivalent capacitance of capacitors C3, C5, and C6 which are connected in parallel. Use the formula:

  • C356 = C3 + C5 + C6 = 3.00 ¬¨¬µF + 6.00 ¬¨¬µF + 3.00 ¬¨¬µF = 12.00 ¬¨¬µF

Then, calculate the equivalent capacitance of C2 and C356 in series:

  • 1/C2356 = 1/C2 + 1/C356
  • C2356 = 4.89 ¬¨¬µF (approx.)

Step 3: Determine Total Capacitance for Figure 2

To find the overall equivalent capacitance for the entire network in Figure 2, combine C1 with C2356, again using the series formula:

  • 1/C_total = 1/C1 + 1/C2356
  • C_total = 1.73 ¬¨¬µF (approx.)

Therefore, the final values for the equivalent capacitances are approximately 2.09 µF for Figure 1 and 1.73 µF for Figure 2.
