Nothing happens. The point labeled "20 v" may well be at 20 volts relative to the
bottom of the battery in the loop, but nothing in the loop has any knowledge or
awareness of ground, so nothing at the "20 v" point has any particular desire to
head for ground.
You might as well connect a resistor from one side of the battery in your cellphone
to ground, and carefully observe the ensuing complete absence of any results.
The door bell contacts are stuck together or corroded or the wires to it are shorted together at some point up to the power supply and bell.
It would depend on the circuit diagram. In some cases, the circuit would be incomplete (simplest case is a battery with a wire attached to just one terminal).Parallel branches that have a connection to the battery without going through other branches are independent of each other. Say you have two parallel branches and a battery. If you short circuit one of the branches, the other branch will not be affected but the battery will be (current through the battery would decrease because taking out a parallel branch increases resistance).In short, it would depend on the circuit diagram. Note that for a nanosecond, there would be current in an open circuit, but after this brief time there would be no current flow in the segment of the circuit that has been shorted.
A circuit is complete whenever current can flow from the battery (or what is producing current), through the circuit, and back to the battery. A complete circuit could contain just a battery and one wire. An incomplete circuit could be a battery with a wire attached to just one terminal, because current cannot flow all the way through the circuit in this case (i.e. cannot flow through the battery). note: not all elements in a circuit may have current flow in a complete circuit. For instance, a light bulb may be shorted but you still have a complete circuit.
resistor R1 is shorted
A contactor not being energized or closed can be caused by a host of reasons . A shorted or open contactor coil. No control voltage or incorrect voltage present to energize the contactor coil , A safety device opening or breaking the control circuit . A loose or broken control devise or control wire . and possibly more , depending on your a/c units control wiring configuration. Tom H, HVAC proffesional. New Orleans .
The door bell contacts are stuck together or corroded or the wires to it are shorted together at some point up to the power supply and bell.
The circuit becomes a pure resistance circuit where current and voltage are in phase with each others.
Short Circuit
Analysing a circuit with a shorted component need specialised electrical test equipment.
In a shorted circuit, the temperature of the wires increases. This is because the wires are not perfect conductors - they have resistance - so the large fault current that flows generates a voltage across the wires, which then generates power, generating heat.
A shorted circuit.
Shorted can show up in three main contexts that I am aware of: To bypass the intended path - like in a short circuit To give less than what is owed To sell unowned stock in (the Stock Market) in anticipation of making a profit when prices fall. Synonyms for "shorted" related to short-circuit: bypassed grounded cross-connected blew a fuse overloaded overwhelmed Synonyms for "shorted" related to giving less than what is owed: cheated swindled victimized swindled rooked defrauded scammed gypped or gipped conned chiseled ripped-off underestimated Synonyms for "shorted" related to stock sales: sold short went short
35 - passenger side air bag circuit low resistance or shorted 53 - intermittent or repaired air bag circuit shorted to ground
In that case, the circuit is shorted, or short-circuited.
A blown fuse indicates a shorted circuit somewhere in the system. Could be a shorted power wire to ground, or a shorted componet in the system.
It depends on weather it is in a parallel or series circuit. In parallel the entire circuit it is in parallel with is shorted out. In series the total resistance decreases by the amount of the resistor that shorted out. Resistors usually open or change value with use.
One word that usually means "not short" is tall. The other major antonym is long.
