Electronic devices. Hand holds an assortment of electronic devices. The devices include resistors (thin with stripes), capacitors (thick), Light- Emitting Diodes (LED, translucent domes) and a transistor (dark grey, at lower centre). Resistors limit the flow of electric current; the stripes on them are a code to show their resistance. Capacitors are used to store charge. LEDs are an efficient way of producing light from an electric current. Transistors are used for current amplification and signal processing.
