How much energy can a capacitor of 470uf store

What does 470uf mean on a capacitor?

This first number indicates the amount of energy the capacitor can handle at a certain voltage. The second number is the voltage rating, which indicates the maximum voltage to which the capacitor can be exposed. For example, if your capacitor reads “470uF 25v,” it can hold 470 micro-farads at 25 volts.

What is the output of capacitor energy calculator?

Another output of the capacitor energy calculator is the capacitor's charge Q Q. We can find the charge stored within the capacitor with this expression: where again: Q Q is the charge within the capacitor, expressed in coulombs. The capacitor energy calculator finds how much energy and charge stores a capacitor of a given capacitance and voltage.

How many volts can a 470 uF capacitor hold?

For example, if your capacitor reads “470uF 25v,” it can hold 470 micro-farads at 25 volts. Twenty-five volts is the maximum voltage allowed for that capacitor. If you subject the capacitor to a voltage rating higher than 25, the capacitor will explode. What is uF? We measure the capacitance rating in microfarads, denoted by uF.

How many 470uf 10V capacitors are left in stock?

Only 10 470uF 10V capacitors are left in stock - order soon.

How much does a 4700uf 25V capacitor cost?

The 4700uf 25V capacitor costs £2.99 for the SNS 4700uF 25V 85C Electrolytic Capacitor Pack of 2, and £5.99 for the SNS 4700uF 25V 105C Electrolytic Snap In Capacitor High Temperature Hitano Pack of 2.

How much energy does a capacitor hold?

He calculates the earth's capacitance at about 0.18 Farad, which seems surprisingly low, and from the known value of charge density at the surface of the earth (around 3 nC/sq.m) he shows that this capacitor holds a million Coulombs or so. Then it's a simple matter to calculate how much energy it's storing.
