Electronic Spices Resistor 27K Ohm 1/4 Watt(100psc) Variable Resistor  (27 ohm 1/4)

This is a resistor, which is an electrical component that resists the flow of electricity. They are usually used in circuits with a circuit board to prevent too much electricity from flowing to one point, which can cause the circuit to malfunction. A resistor is a passive two-terminal electrical component that implements electrical Resistor as a circuit element.
