1.The shunt resistor is a device which could help DC ammeter for measuring high current. Technically, a shunt needs to be connected in parallel with the ammeter (Current division in parallel circuit)2.Shunt Resistor helps the ammeter to bypass majority of current. Based on the principle of Ohm Law, the current could be calculated by DC ammeter when a shunt drops the voltage.3.If there were any challenges might confuse you.
