Variable resistor
Variable resistor. Also known as a rheostat, this image shows the internal workings of a variable resistor. When placed in a circuit, electricity travels through the coil and out through the metal pointer (lower right). By turning the central dial, the position of this pointer on the coil can be altered to control the amount of coil, and hence resistance, in the circuit

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate internal workings of a variable resistor, also known as a rheostat. The image reveals the technological marvel hidden within this electronic device. A coil, positioned at the center of the photograph, serves as the main component through which electricity flows when placed in a circuit. As it travels through the coil, electricity exits via a metal pointer located in the lower right corner. What makes this variable resistor truly fascinating is its ability to control resistance within an electrical circuit. By simply turning the central dial depicted in this image, one can alter the position of the metal pointer along the coil. This adjustment directly impacts and regulates both current flow and resistance levels within said circuit. The single non-integrated design showcased here emphasizes simplicity while maintaining effectiveness. With its physical structure clearly displayed, viewers gain insight into how physics and electronics seamlessly merge to create such essential components for various applications. Science enthusiasts will undoubtedly appreciate this snapshot's focus on detail and precision engineering. It serves as a reminder that even seemingly small devices like resistors play significant roles in our modern technological landscape by enabling us to manipulate electrical currents with ease and accuracy.
