谁能告诉我如何计算这道电路题
Special shunt resistors designed to drop 50mV in high current-measuring applications are available from manufacturers. A 50mV, 10K ohm full-scale voltmeter is connected across the shunt to make the measurement.
1.What value of shunt resistance is required to use a 50mV meter in a 50A measurement application?
2. How much current is through the meter?
谁能告诉我运算过程,谢谢.

1.value of shunt resistance is：50mV Dive 50A,the result is 0.001
2.current through the meter is:50A*(0.001*10000/(0.001*10000)),the result is 0.0009999999 ,about to 1mA
2.current through the meter is:50A*(0.001*10000/(0.001*10000)),the result is 0.0009999999 ,about to 1mA
