🔍 Key Concepts

• Electrical power and heating in conductors (Joule’s law) • Relationship between current, resistance, and power (P = I²R and P = V²/R) • Difference between something being directly proportional to a variable vs. involving that variable but in a different way

💭 Think About

• Think about the formula that relates the heat (or power) produced in a resistor to current and resistance. Which variables appear, and how? • Does heat increase linearly with current, or with the square of the current, when resistance is constant? • If you double the resistance while keeping current constant, what happens to the heat produced? If you double the current while keeping resistance constant, what happens?

✅ Before You Answer

• Identify the correct form of Joule’s law for heat developed in a resistor: H = ? • Check whether heat is directly proportional to resistance, or only proportional when other variables are held constant. • Check whether heat is directly proportional to the current or to the square of the current in the standard heating relationship.
