  • Question 4
    4 / -1

    By a cell a current of 0.9 A flows through 2 ohm resistor and 0.3 A through 1 ohm resistor. The internal resistance of the cell is

  • Question 5
    4 / -1

    A student measures the terminal potential difference(V) of a cell (of e.m.f E and internal resistance r) as a function of the current (I) flowing through it. The slope, and intercept, of the graph between V and I,then, respectively, equal
