by closing them
Electricity can travel in both closed circuits and open circuits. In closed circuits, there is a complete loop for the electricity to flow through, allowing devices to receive power. Open circuits, on the other hand, have a gap that interrupts the flow of electricity.
Both open and closed circuits involve the flow of electric current. In an open circuit, the current is interrupted or stopped due to a gap in the circuit, while in a closed circuit, the current flows continuously through a complete loop of conductor.
parallel circuitsThey could be called twin-loop circuits but it isn't a term in common use.
if we set timimg for cooking rice then it is open loopbut thermostat in electric cooker can not give more temmp, than 100deg. so some microprocessor is controlling here .thus in this case it will act as closed loop system.
loop checking is perform before cable termination..the difference between a close loop and open loop is,tha close loop has a feedback while the open loop has not.
Circuits need to maintain a closed loop to allow the flow of electric current. If the loop is broken, the current cannot flow, and the circuit will not work. This is essential for the proper functioning of electrical devices and systems.
KVL (Kirchhoff's Voltage Law) can be applied to open circuits, where the sum of voltages around a loop is zero. KCL (Kirchhoff's Current Law) can also be applied to short circuits, where the sum of currents at a node is zero. However, in these cases, the analysis may not reveal meaningful or useful information due to the extreme nature of open or short circuits.
it is when a control loop is open and processing
The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
an open circuit.
The system without feedback is known as open loop system. The examples of the open loop system are bread toaster, oven ,washing machine. The open loop systems are inaccurate & less complex.
The open loop system is simple and economicaleasier to constructstable
