Question: What is Ohm\'s Law?

Options:

  1. V = I * R
  2. P = V * I
  3. I = V / R
  4. R = V / I

Correct Answer: V = I * R

Solution: 

Ohm\'s Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with the resistance (R) being the constant of proportionality.

Questions & Step-by-Step Solutions

What is Ohm's Law?
  • Step 1: Understand that Ohm's Law is a basic principle in electricity.
  • Step 2: Know that it relates three important concepts: voltage (V), current (I), and resistance (R).
  • Step 3: Remember that voltage (V) is the electrical force that pushes current through a conductor.
  • Step 4: Understand that current (I) is the flow of electric charge in a circuit.
  • Step 5: Recognize that resistance (R) is the opposition to the flow of current.
  • Step 6: Learn the formula for Ohm's Law: V = I × R.
  • Step 7: Realize that if you know any two of these values (V, I, R), you can calculate the third.
  • Ohm's Law – Ohm's Law describes the relationship between voltage, current, and resistance in an electrical circuit.
