If electricity passes through a system at 12 volts, with 0.42 Amps of current, and 28.8 ohms of resistance, how do you calculate the energy lost in joules?

Resistance refers to the opposition that a material or object presents to the flow of electricity. It can be thought of as a force that slows down the movement of electric charges and converts some of their energy into heat.
Resistance causes a decrease in the flow of electrical current, which in turn reduces the amount of energy that can be transferred. This is because some of the electrical energy is converted into heat as it encounters resistance in a circuit.
Several factors contribute to energy loss due to resistance, including the material of the conductor, length and thickness of the wire, and temperature. Materials with higher resistance, longer wires, and smaller diameters will result in more energy loss.
While it is impossible to completely eliminate energy loss due to resistance, it can be minimized through the use of materials with low resistance, shorter and thicker wires, and keeping temperatures low. Additionally, proper maintenance and regular checks of electrical systems can help reduce energy loss.
The energy lost due to resistance can be calculated using Ohm's Law, which states that the amount of energy lost is equal to the square of the current multiplied by the resistance. It can also be measured using a multimeter, which can provide the resistance value and calculate the energy loss.
