What is the capacitance of the capacitor if the charge of the capacitor is 10 nC and the voltage is 20 kV?
| September 1, 2021 | education
To find the value of the electrical capacity of the specified capacitor, you must apply the formula: C = q / U.
Constants and variables: q – charge value (q = 10 nC = 10-8 C); U is the effective voltage across the capacitor (U = 20 kV = 2 * 10 ^ 4 V).
Calculation: C = q / U = 10 ^ -8 / (2 * 10 ^ 4) = 0.5 * 10 ^ -12 F.
Answer: The indicated capacitor, according to the calculation, has an electrical capacity of 0.5 pF.
