Question on: SS2 Physics - Electronics

Resistors are passive electronic components that are used to restrict the flow of electric current in a circuit. They are primarily used to control the voltage and current levels within a circuit and to provide stability. Resistors come in different types, including fixed resistors and variable resistors. Fixed resistors have a constant resistance value, whereas variable resistors (potentiometers) allow the resistance to be adjusted. Resistors affect the flow of current by creating a voltage drop across them, according to Ohm's Law (V = I x R). They dissipate power in the form of heat, and their resistance is measured in ohms (Ω).
