What happens to a circuit if there is no resistance?

Ideally, if there is no resistance ,i.e, short circuit is connected across an dc source, infinite current will flow as I=V/R, and R=0. Practically, if you connect a wire directly across a battery, it will start heating. Resistance of short wire is in the range of Ohms which is very less as compare to resistors.

What does it mean when there is no resistance?

Resistance, symbolized by the (Ω) symbol and measured in Ohms, is a measurement of how well a current can travel through a circuit or a given path. A circuit with no resistance (0) would indicate a complete circuit, or one that has no short.

Can there be voltage if there is no resistance?

Voltage can certainly exist without resistance. If you have an electric field in empty space (or, for example, in a capacitor) there will be a potential difference even though there are no resistors around.

Do all conductors have resistance?

The Wire Wisdom “Conductors – The Electron Superhighway” discussed different size conductors and the reasons for their existence. This Wire Wisdom will examine how resistance affects wire and cable. All Objects Have Resistance. The best conductors in the world, excluding superconductors, have some resistance.

Why is it not advisable to connect a circuit with no resistors?

That final energy is usually what is dissipated as heat or other types of energy by the circuit. But without resistance (or inductance) it won’t have a chance to lose the energy, and will return to the voltage source with lots of energy, which will typically screw up the voltage source.

What happens to current in the presence of resistance in the connecting wire?

The current is therefore inversely proportional to the resistance: I∝1R I ∝ 1 R .

What is resistance in a current?

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
