Oh, dude, like, you want that earthing circuit to have low resistance so it can quickly divert any unwanted electrical currents to the ground, you know? It's like giving those pesky electrons a speedy highway to escape instead of causing chaos in your appliances or, worse, in you! So yeah, low resistance in the earthing circuit is crucial for safety and keeping things running smoothly.

MaxineThe purpose of an earthing (protective) conductor in a residential installation is to allow sufficient fault current to flow, in the event of an earth fault, to enable the operation of the circuit's overcurrent protection device (fuse or circuit breaker), so its resistance must be sufficiently low to allow this to happen.

Is the current pass through parallel short resistance?
no.because current always try to flow trough low resistance path.as short circuit has low resistance current pass trough short circuit
A dangerous circuit with low resistance and high current?
Another name for a circuit with low resistance and high current is a short circuit. It is dangerous because, if you have sufficient energy in the power source, you can damage components and/or cause fires.
Why is grounding important?
Every electrical system should be earthed to get a low resistance path for dissipation of current into the earth. Major accidents take place because of improper equipment earthing or leakage current. Earth fault current directly affect the human safety. Earthing should be measured at regular intervals so as to ensure that the resistance of the earth is maintained minimum. Its main purpose is to minimize the risks of fire and shock hazards.
What will happen if a voltmeter has a low shunt resistance instead of having high shunt resistance?
The purpose of a voltmeter is to indicate the potential difference between two points in a circuit.When a voltmeter is connected across a circuit, it shunts the circuit. If the voltmeter has a low resistance,it will draw a substantial amount of current. This action lowers the effective resistance of the circuit andchanges the voltage reading.
If a parallel circuit shorts at the battery will the entire circuit short out too?
If at battery,parallel circuit shorts then equivalent resistance of circuit becomes approximately 0 Ohms,and therefore as current follows low resistance path infinite amount of current due to low resistance will flow through the wire so,entire parallel circuit will short out,but wire will burn and battery may get damaged.
