The 47K ohms (2 watt) resistor is a high-resistance component with a resistance value of 47,000 ohms, capable of handling up to 2 watts of power. It is used in electronic circuits to control current flow, divide voltages, and stabilize circuit performance. The 2-watt power rating allows it to manage higher power dissipation without overheating, making it suitable for applications requiring both high resistance and significant power handling, such as in power supplies, voltage dividers, and high-impedance circuits.
