Definition
- Noun:
- The reciprocal of capacitance: In electrical engineering and physics, "elastance" is a property of a capacitor, defined as the inverse of its capacitance. It measures the opposition to a change in voltage. The SI unit of elastance is the daraf (farad spelled backward).
Usage Examples
- Noun:
- The elastance of the capacitor is crucial for tuning the resonant frequency of the circuit.
- A high elastance value indicates a capacitor that requires a large change in voltage for a small change in stored charge.
Advanced Usage
- "Elastance" is a specialized technical term primarily used in theoretical analyses and specific engineering contexts, such as when describing the behavior of capacitive systems in terms of voltage per unit charge, rather than charge per unit voltage (capacitance).
Variants and Related Words
- Capacitance (n): The ability of a system to store an electric charge per unit voltage. It is the direct reciprocal of elastance.
- Daraf (n): The unit of measurement for elastance, equal to the reciprocal of a farad (F⁻¹).
Synonyms
- Electrical stiffness: A descriptive synonym highlighting the concept's relation to opposition against voltage change.
- Inverse capacitance: A direct descriptive synonym.
Related Terms (Technical Context)
- Permittivity (n): A material property that influences capacitance and, consequently, elastance.
- Reactance (n): The opposition to current flow in AC circuits due to capacitance or inductance; elastance is a related property for capacitors.
Noun
