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.
A sudden fail-open fault can cause multiple secondary failures if it is fast and the circuit contains an inductance; this causes large voltage spikes, which may exceed 500 volts. A broken metallisation on a chip may thus cause secondary overvoltage damage. [1] Thermal runaway can cause sudden failures including melting, fire or explosions.
For example, if you have a 56kbs dial-up connection to the internet, you will be able to watch videos with a bit rate of 56kbs or less. (A majority of dial-up connections have speeds of 28kbs or less because of issues with the phone lines). If you try to watch a video clip with a bit rate of 300kbs over a dial-up connection, the video will not ...
For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and ...

A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.
LONDON — The world is entering a “third nuclear age,” the head of the British armed forces has warned, with world-ending weapons once again spreading globally and international agreements to ...
Bill Clinton “Hillary and I mourn the passing of President Jimmy Carter and give thanks for his long, good life,” Clinton, the country's 42nd president, said in a statement on Sunday.
