# Find the equivalent capacitance

We can find an expression for the total (equivalent) capacitance by considering the voltages across the individual capacitors. The potentials across capacitors 1, 2, and 3 are, respectively, V1=Q/C1, V2=Q/C2, and V3=Q/C3.Feb 20, 2022

## How do I find equivalent units?

How do you find equivalent units? Equivalent units. are calculated by multiplying the number of physical (or actual) units on hand by the percentage of completion of the units. If the physical units are 100 percent complete, equivalent units will be the same as the physical units.

## How do you find a fraction that is equivalent?

What are equivalent fractions?

• Sometimes fractions can be simplified into smaller ones.
• These fractions are said to be equivalent.
• You can multiply the numerator and denominator in the smaller fraction, by the same number, and get the first fraction back.
