Answer:
A derived quantities is terms of the 7 base quantities via a system of quantity equations which are called SI derived units.
Explanation: there you go:)
 
        
             
        
        
        
The energy is 3.06 electronvolts,  E = 3.06eV
1eV = 1.6 * 10^-19 J
3.06 eV = 3.06* 1.6 * 10^-19 J = 4.896 * 10^-19 J
        
             
        
        
        
The relationship between amperage, voltage, and power is that power equals the amperage quantity times the amount of voltage. 
Power: is the amount of energy transferred or converted per unit time.
