Problem Statement

What is resistance?

Step-by-Step Explanation

Resistance measures how strongly a material or component opposes electric current.

  1. Identify what the question is asking. In Circuits, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
  2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
  3. Work one step at a time and keep units, signs, and restrictions visible.
  4. Check whether the answer makes sense in the original context.

Key Formula

R=VIR=\frac{V}{I}

Final Answer

Resistance measures how strongly a material or component opposes electric current. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
