Web1 de mar. de 2024 · An open circuit is defined as an electric circuit in which current does not flow. Current can only flow in a circuit if it finds a continuous path—known as a “closed circuit”. If there’s a break anywhere in the circuit, you have an open circuit, and current can not flow. In an open circuit, the two terminals are disconnected. WebSo, I would imagine a small current flowing over here and see if that entire current flows here. If it does, they are in series. If not, they're not in series. So, imagine some current …

Web22 de nov. de 2024 · The LM339 has an ' Open Collector ' output. When IN+ is higher then IN- its output transistor is turned off to become 'high impedance', so it does not draw significant current from R13. The MCU input probably also has very high impedance, so current through R13 will be very small and the voltage will be close to 3.3V. Web11 de set. de 2016 · Ohm's law states that voltage=current x resistance, or re-arranging with simple algebra, current=voltage / resistance (resistance is actually impedance, but trying to keep things simple). Therefore, your current can be calculated if you know the voltage and the resistance in the circuit.
