The formula to calculate the resistor heat is:
\[ \text{RH} = I^2 \cdot R \cdot t \]
Where:
Resistor heat refers to the amount of heat energy generated by a resistor when an electric current passes through it. This heat is a result of the electrical energy being converted into thermal energy due to the resistance.
Example:
Step 1: Calculate the resistor heat:
\[ \text{RH} = (2^2) \cdot 5 \cdot 3 = 4 \cdot 5 \cdot 3 = 60 \text{ watt-hours} \]
