Yes, resistors do obey conservation laws. This means that the total amount of energy entering a resistor must equal the total amount of energy leaving the resistor, according to the law of conservation of energy.
Resistors obey conservation laws through the conversion of electrical energy into heat energy. When current passes through a resistor, it encounters resistance, which causes the electrical energy to be converted into heat energy. This heat energy is then dissipated into the surrounding environment, ensuring that the total energy entering and leaving the resistor remains equal.
No, there are no exceptions to resistors obeying conservation laws. This is a fundamental law of physics that applies to all objects, including resistors. However, certain factors such as temperature and material properties can affect the amount of energy that is converted into heat in a resistor.
If a resistor does not obey conservation laws, it would violate the law of conservation of energy. This means that the total amount of energy entering the resistor would not equal the total amount of energy leaving it, which would go against the basic principles of physics.
In circuits with multiple resistors, conservation laws still apply. The total energy entering the circuit must equal the total energy leaving the circuit, which means that the sum of the energy dissipated in each resistor must be equal to the total energy supplied by the power source. This is known as Kirchhoff's second law, or the law of conservation of charge.
