Calculate the value of resistor, Electrical Engineering

Calculate the value of resistor:

1.  What are the significant differences in the way ammeters and voltmeters are connected. If an ammeter reads 2.5 A for a period of 4 minutes, determine the charge that has passed through the ammeter.  

2.  Calculate the value of resistor x and the current passing through it.
