In a series circuit, the current is the same at every point, so the current through the 6-ohm resistor is also 4 Amperes.  Voltage across a resistor =                    (current through the resistor)                times                    (resistance of the resistor)  . Voltage across the 6-ohm resistor =                    (4 Amperes) x (6 ohms)  =  24 volts .
