The voltage v oc between the terminals is the open-circuit voltage of the device. Black curve: The highest possible open-circuit voltage of a solar cell in the Shockley-Queisser model under unconcentrated sunlight, as a function of the semiconductor bandgap. The red dotted line shows that this voltage is always smaller than the bandgap voltage.
Closed-circuit television (CCTV), also known as video surveillance, [1] [2] is the use of closed-circuit television cameras to transmit a signal to a specific place on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point , point-to-multipoint (P2MP), or ...
Open-circuit voltage, the difference of electrical potential between two terminals of a device when there is no external load connected; An electrical circuit is an "open circuit" if it lacks a complete path between the terminals of its power source
An electrical contact is an electrical circuit component found in electrical switches, ... Where a switch contains both normally open (NO) and normally closed (NC ...
Closed-circuit radio; Closed circuit breathing apparatus, commonly known as rebreathers for portable units, and as component parts of life-support systems for more complex equipment. Closed Circuit, a 1978 Italian film; Closed Circuit, a 2013 British thriller film; An electric circuit is a "closed circuit" if it contains a complete path between ...
For example, if we use an input resistance to represent the load, the complete circuit looks like this: The input resistance of the load stands in series with Rs. Whereas the voltage source by itself was an open circuit, adding the load makes a closed circuit and allows charge to flow.
A simple electric circuit made up of a voltage source and a resistor. Here, =, according to Ohm's law. An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances ...
The reflection from a short-circuited line can be described in similar terms to that from an open-circuited line. Just as in the open circuit case where the current must be zero at the end of the line, in the short circuit case the voltage must be zero since there can be no volts across a short circuit.
