Understanding a Shunt

A shunt is used to find the current in a circuit if the current is too big for the ampmeter. The precise 1 ohm resistor is placed with the voltmeter in parallel in the circuit. Since i=v/r,  i = volt/1.
This is usefull for measuring anything above 20 amps as general multimeter can not measure such high amps.

I dont think the 1Ω resistor will allow such high currents to flow, have you considered what the damages will be from all that heat?

P=V^2 × R, I know the resistor should be much lower than this. This is just an example for understanding shunt. And easy calculation.
