// Using relation V = E - I*R and substituting the values of I_1, I_2 and I_3 one by one in it

// Result
// The terminal potential difference developed across resistor for a current of 0.5 A = 5.925 V
// The terminal potential difference developed across resistor for a current of 2 A = 5.7 V
// The terminal potential difference developed across resistor for a current of 10 A = 4.5 V
