Resistance Value (1K ohm): This indicates the nominal resistance of the resistor, which is 1000 ohms. The symbol “K” represents kiloohms, so 1K is equivalent to 1000 ohms.
Power Rating (1/4 watt): This specifies the maximum power the resistor can dissipate without getting damaged. In this case, the power rating is 1/4 watt, which means the resistor can handle up to 0.25 watts of power.
Tolerance (5%): The tolerance indicates the range within which the actual resistance of the resistor may vary from its nominal (specified) value. A 5% tolerance means that the actual resistance could be 5% higher or 5% lower than the specified 1K ohm. For a 1K ohm resistor with a 5% tolerance, the actual resistance may fall between 950 ohms and 1050 ohms.
Type of Resistor (Carbon Film): This indicates the construction of the resistor. In this case, it’s a carbon film resistor. Carbon film resistors are made by depositing a thin film of carbon on a ceramic rod, and they are commonly used in electronic circuits.
Color Code: The color code is a visual representation of the resistor’s value and tolerance. The color bands on the resistor help you identify its resistance value and tolerance.
