Which part of an electric circuit resists the flow of charge when it changes electrical energy into other forms of energy?
A. battery
B. copper wires
C. switch
D. light bulb
i don't think its C but i'm not sure about the others :(
The part of an electric circuit that resists the flow of charge and converts electrical energy into other forms of energy is the light bulb. The correct answer is option D.
To understand this, let's break down the components of a simple electric circuit. In a circuit, we typically have a power source, which is often a battery (option A). The power source provides the electrical energy to the circuit and maintains a potential difference, or voltage, across the circuit.
Copper wires (option B) are commonly used conductors in electric circuits. They allow the flow of electric current with minimal resistance. However, copper wires do not typically convert electrical energy into other forms of energy, so they are not the answer.
A switch (option C) is a device used to control the flow of current in a circuit. While it can interrupt or allow the flow of current, it does not convert electrical energy into other forms of energy.
The light bulb (option D), on the other hand, is a component that converts electrical energy into light and heat. When current flows through a light bulb, it passes through a filament, which heats up and produces light as a result of the electrical energy conversion. Thus, the light bulb is the part of the circuit that resists the flow of charge and changes electrical energy into other forms of energy, making option D the correct answer.
