470000ohm

470000ohm, often written as 470 kΩ or 470k, refers to a specific resistance value. In electronics, resistance is a measure of how much a material opposes the flow of electric current. The unit of resistance is the ohm, symbolized by the Greek letter omega (Ω). The prefix "kilo" (k) denotes a multiplier of one thousand. Therefore, 470000 ohms is equivalent to 470,000 ohms, or 470 kilohms.

This resistance value is commonly found in electronic components, most notably resistors. Resistors are used to control current flow, divide voltage, and dissipate energy in electronic circuits. A 470kΩ resistor would be used in applications where a moderate level of resistance is required. The precise application depends on the overall circuit design and the intended function. For example, it might be used as a pull-up or pull-down resistor, in a filter circuit, or as part of a voltage divider.

The tolerance of a 470kΩ resistor is also an important characteristic. Tolerance indicates the permissible deviation from the stated resistance value. Common tolerances for resistors include 5% and 1%. A 470kΩ resistor with a 5% tolerance could have an actual resistance anywhere between 446,500 ohms and 493,500 ohms. For more critical applications requiring higher precision, resistors with tighter tolerances like 1% or even lower would be selected. The color code band on a resistor or markings on the component itself would indicate its resistance value and tolerance.
