Question: What is the relationship defined by Ohm\'s Law?

Options:

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

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 the relationship defined by Ohm's Law?
Correct Answer: V = I * R
  • Step 1: Understand that Ohm's Law is a rule in electricity.
  • Step 2: Know that it relates three important things: 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 the conductor.
  • Step 5: Recognize that resistance (R) is the opposition to the flow of current.
  • Step 6: Learn the formula: V = I * R, which means voltage equals current times resistance.
  • Step 7: Realize that if you increase the current, the voltage will also increase if resistance stays the same.
