Circuit Symbols and the Voltage Divider

▶ شغّل المحاكاة

Every symbol in the lecture as a real 3D component on a bench — knife switch, cartridge fuse, moving-coil meters, ceramic resistor, wound rheostat. Click any one to see the symbol you would draw for it, slide the rheostat to share the 12 V, and push the current far enough to blow the fuse.
