What is the resistance of a short circuit in ohms called?

Answer 1

Your original question was in two parts:
1.) How many ohms in an open circuit? Infinite ohms (the meter will show no measurement).
2.) How many ohms in a short circuit? 0 ohms. There would be no measurable ohms as there would be no resistance in the altered circuit.

Answer 2

There are no Ohm's in a shorted circuit. An Ohm is a measure of the circuits resistance to current. A shorted circuit is a circuit - by definition - wherein the flow of current is unopposed - and thus very high.

Consider the simplest of all circuits: A battery, an LED, and a resistor. The LED is lighted by the current flow from the battery. The resistor resists a certain amount of current flow so that the current from the battery does not exceed the amount of current the LED needs to light and not be burnt out - (or more technically, open).

If you were to take the resistor out of this simple circuit, you would essentially have a short circuit. In practice, short circuits are usually caused by a failure of a component to resist the flow of current.

Think of it this way:

A "Short Circuit" is a complete failure to oppose the flow of current. There IS NO resistance and therefore no Ohm's. (Ohm's is the measurement for resistance).

An "Open Circuit", (the opposite of a short circuit) is a circuit where a component is defective and completely obstructs the flow of current due to there being a physical break, or open, in the circuit. Imagine a simple light switch in a house. When you flip the switch and the light turns on, the circuit is closed, current can flow, and the bulb lights. When you flip the switch and turn off the light, the switch physically OPENS the circuit. When you open the circuit, you break the path of the circuit and current cannot flow.

The short answer to your question is thus:

There is no measurement of resistance in a shorted circuit - as measured in Ohm's - because there is no resistance to current flow to measure.

Answer 3

It depends on the multimeter error. An ideal meter would read '0' for a perfect short.

Answer 4

A short circuit has no resistance. that's what is meant by the term "short circuit". This causes massive current flow since I = V / R. In a short, R is approaches zero.

Answer 5

It's a term for grounding a hot wire causing a "short".

Answer 6

A short circuit can be identified using the ohmmeter when its reading is zero.

Answer 7

Short circuits generally don't have any resistance.

Answer 8

A short circuit has a resistance equal to zero. Of course, some people think that the number zero does not exist and therefore state that a short circuit has no resistance.

Answer 9

Usually, very close to zero.

Answer 10

zero ohms
