What is the relationship between voltage, current, and resistance according to Ohm's Law?
V = I * R
V = I / R
V = R / I
V = I + R
Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with resistance (R) as the proportionality constant: V = I * R.

Q
Q: What is the relationship between voltage, current, and resistance according to Ohm's Law?
Solution: Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with resistance (R) as the proportionality constant: V = I * R.
Steps: 5
Step 1: Understand that voltage (V) is the electrical force that pushes current through a conductor.
Step 2: Know that current (I) is the flow of electric charge in a circuit.
Step 3: Recognize that resistance (R) is the opposition to the flow of current in a conductor.
Step 4: Learn that Ohm's Law connects these three concepts with the formula V = I * R.
Step 5: Realize that if you know any two of the values (V, I, R), you can calculate the third one using this formula.
