# Resistance vs. Capacitance: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 24, 2023
Resistance opposes electrical flow, measured in ohms; capacitance stores electrical energy, measured in farads.

## Key Differences

Resistance is a property of a material or device that impedes the flow of electric current, often quantified in ohms. Capacitance, on the other hand, is the ability of a system to store an electric charge, measured in farads.

In resistance, the higher the value, the more it resists the current flow; it's a factor in determining how much current flows for a given voltage. Capacitance represents how much electric charge is stored for a given electric potential, influencing how a circuit responds to changes in voltage.

Resistors, the components that provide resistance, dissipate energy in the form of heat, whereas capacitors, which provide capacitance, store energy temporarily without loss. This fundamental difference reflects their distinct roles in circuits.

The concept of resistance is crucial in designing circuits to control current flow, protect components, and manage power dissipation. Capacitance is key in timing applications, filtering signals, and energy storage in electronic circuits.

Resistance and capacitance both affect an AC circuit's impedance, but in different ways: resistance dissipates energy, while capacitance stores and releases it cyclically, leading to phase shifts between current and voltage.
