An open (circuit) is where insufficient (often zero) current flow where some is expected. In this case, little or no work is done.
A short (circuit) is where high (often infinite or as limited by the power supply) current flows where only some is expected. In this case also, little or no work is done by the device intended, but there is enough current to trip (or blow) the protective device (fuse or circuit breaker).
A short is an unexpected low impedance connection in a circuit, causing fault current to flow. It usually trips the protective device in the distribution panel.
An open is an unexpected high impedance (lack of) connection in a circuit, causing no current to flow. It usually does not trip the protective device in the distribution panel.
The difference between 1 second and 3 seconds is 2 seconds. In terms of short-circuit withstand capacity, it can mean the difference between no damage and damage occurring to the equipment and wiring. Heat rises extremely fast in a short-circuit situation, and you want your protective device to trip before damage is done.
An open circuit has a break in it somewhere, so the circuit is not complete and electricity cannot flow. When you power off a light, for example, with an on/off switch, you open the circuit, turning off the light as desired. When there is an unwanted open circuit, for example from a damaged wire, the device or system is unpowered and cannot operate. A short circuit has some unwanted contact between points at different voltage levels, such as from hot to neutral or ground, or between positive and negative. When a short is in a circuit, electricity will take only that path of little or no resistance. The rest of the system is deprived of power, and the conductors feeding the point of the short will likely overheat or burn unless a fuse or breaker operates, creating now an open circuit.
A short circuit is an abnormal connection between two nodes intended to be at different voltages. A voltage circuit is caused intentionally for the purpose of voltage sensing. A ground circuit occurs between a phase and the ground.
'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.
normally close relay is closed initially and when a signal arrive to it it will open and dont let the current pass i9n opposit to normally open
difference between short,near and far jump
the difference between installment credit and open ended credit is they are the same..
the long term is different between a short term because the short
difference between miliary tuberculosis and tuberculosis
Related to a battery and open load is the battery just sitting there without anything connected. A short is a very low resistance attached to the tow terminals of the battery. For example, a wire connected across the battery terminals would constitute a short.
nothing
There is no difference. Limo is just short for limousine.
one is open and the other is closed
there is no difference. they are both 42.
The difference between the short and long carbon cycle is that the short cycle emphasizes the interaction between the biosphere and atmosphere while the long cycle emphasizes the formation and destruction of fossil fuels.
well there is no difference
Their length.
