if it is desired to limit the current in a 50 ohm resistor to 10A when it is connected to a 600V power source. how should and auxiliary resistor be connected in the circuit and what should it's resistance be?

Expert Answer:

From Ohms law , we know that
 where V is the voltage and I is the current and R is the resistance.
Therefore in order to limit the current to 10A, we need to connect the auxilary resistor of resistance 10 ohms in series with the 50 ohm resistor and this will make the equivalent resistance be 60 ohms .
