# Resistance

- Joule's Law - Heating Effect of Electric Current - Learn about Joule's Law and the calculation of heat energy produced by an electric current through a resistor over a period of time. Understand the relationship between heat energy, electrical resistance, and time.
- Motor Winding Resistance - Calculate the total resistance of motor winding by multiplying the resistance per unit length of the wire by its total length. Essential for electrical motor design.
- Ohm's Law - Ohm's Law relates the current flowing through a conductor to the voltage and resistance, fundamental in electrical engineering.
