Step by step:

  • Voltage Calculation: V = Q / C
  • Charge: 110µC = 0.00011C
  • Capacitance: 22µF = 2.2E-5F
  • Voltage: V = 0.00011C / 2.2E-5F = 5V

result:

  • Voltage: 5V

Example 3: Calculate Voltage (V = Q/C)

With a capacity of 22 µF, a capacitor can store a charge of 110 µC. The capacitor is subjected to what voltage across its surface?
Input
Enter 22 in capacitance and 110 in charge.
Formula

  • Voltage: 5V

Example 4: Calculate Energy (E = ½CV²)

Determine the amount of energy that is stored in a capacitor with a 47 µF capacity that is linked to a source of 5 V.
Input
Enter 47 in capacitance and 5 in voltage.
Formula
E = ½ CV²

Step by step:

  • Energy Calculation: E = ½CV²
  • Capacitance: 47µF = 4.7E-5F
  • Voltage: 5V
  • Energy: E = ½ × 4.7E-5F × (5V) ² = 0.0005875J = 0.5875mJ

result:

  • Energy: 0.588mJ
  • Energy joules: 0.000588J

Example 5: Capacitors in Series

A series connection is made between three capacitors, each with a capacitance of 10 µF, 22 µF, and 33 µF. Do you know the overall capacitance of the system?
