Question

if you keep the voltage constant in a circuit and add another resistor to add what will happen to the current​

Answer 1

Explanation:

If you increase the resistance of the load of constant current supply, the voltage will drop proportional to the change in resistance. This change can be calculated by the potential different across the load thus: p.d.=r×I=change in voltage of the main supply. Therefore v-Ir=V(Resultant voltage).
