By introducing resistance, they can limit the current to safe levels, preventing damage to sensitive components. For example, in an LED circuit, a resistor is used to ensure that the current does not exceed the LED's maximum rating. B. The Relationship Between Voltage, Current, and ResistanceAs per Ohm's Law, the relationship between voltage, current, and resistance is fundamental to understanding how resistors function. When a voltage is applied across a resistor, it creates a current that flows through it. The amount of current is determined by the resistance value; higher resistance results in lower current for a given voltage. C.

Resistors are available in a wide range of values, from fractions of an ohm to millions of ohms (megaohms). B. ToleranceTolerance indicates how much the actual resistance value can vary from the stated value. It is expressed as a percentage and is crucial for precision applications. Common tolerance values include ±1%, ±5%, and ±10%. A lower tolerance indicates a more precise resistor. C. Power RatingThe power rating of a resistor indicates the maximum power it can dissipate without overheating. Common power ratings include 1/8W, 1/4W, 1/2W, and 1W. Selecting a resistor with an appropriate power rating is essential to ensure reliability and prevent failure. D. Temperature CoefficientThe temperature coefficient indicates how much a resistor's resistance changes with temperature. It is expressed in parts per million per degree Celsius (ppm/°C). Resistors with a low temperature coefficient are preferred in precision applications, as they maintain their resistance value over a range of temperatures. V. Resistor Color Code A. Explanation of the Color Coding SystemResistors are often marked with colored bands that indicate their resistance value, tolerance, and sometimes temperature coefficient. This color coding system allows for easy identification of resistor specifications. B. How to Read Resistor Color CodesThe color code consists of four or five bands. The first two (or three) bands represent significant digits, the next band represents the multiplier, and the last band indicates tolerance. For example, a resistor with bands of red, red, brown, and gold would have a resistance of 22 ohms with a tolerance of ±5%. C. Examples of Common Resistor ValuesCommon resistor values include 1Ω, 10Ω, 100Ω, 1kΩ (1,000Ω), and 10kΩ (10,000Ω). Understanding how to read these values is essential for selecting the right resistor for a circuit. VI. Applications of Resistors A.
