The current is like the amount of water flowing through a pipe. integrated circuits contain what is known as an “equivalent circuit,” which is a schematic diagram of the circuit function contained in the IC if you tried to build it using discrete components. Batteries and Circuits Two things are needed to make a an electricity do something useful: 1) a source of electrical potential to provide the power, 2) a complete circuit round which electricity can flow. These circuits are mostly small and easy to built designs using minimum number of components. The LED illuminates when the circuit detects a high amplitude waveform. accept a charge. Keywords. When a circuit is connected a current will flow round the circuit. At normal temperature, the resistance of the Thermistor (TH1) is approximately 10 kilo-ohms, which reduces to a few ohms as the temperature increases beyond 100 C.
