Q1
What is the relationship between voltage (V), current (I), and resistance (R) according to Ohm's Law?
  1. V = I * R
  2. I = V * R
  3. R = V / I
  4. V = R / I

Questions & Step-by-Step Solutions

What is the relationship between voltage (V), current (I), and resistance (R) according to Ohm's Law?
  • Step 1: Understand that voltage (V) is the electrical force that pushes current through a circuit.
  • Step 2: Know that current (I) is the flow of electric charge in the circuit.
  • Step 3: Recognize that resistance (R) is the opposition to the flow of current in the circuit.
  • Step 4: Learn that Ohm's Law states the relationship between these three: V = I * R.
  • Step 5: This means that if you know any two of the values (V, I, R), you can calculate the third.
