How to calculate the potential difference across a resistor?
Understand the Problem
The question is asking for the method to calculate the potential difference (voltage) across a resistor, which typically involves using Ohm's Law, stating that voltage (V) is equal to the current (I) flowing through the resistor multiplied by the resistance (R).
Answer
V = I * R
The final answer is V = I * R
Answer for screen readers
The final answer is V = I * R
More Information
Ohm's Law is fundamental in electrical circuits and states that the voltage across a resistor is directly proportional to the current flowing through it. This relationship is crucial for designing and analyzing circuits.
Tips
Common mistakes include confusing the units of measurement or mixing up the formula. Ensure you use consistent units and correctly apply Ohm's Law.
