Two sources of equal emf are connected to an external resistance R. The internal resistance of the two sources are` R_(1) and R_(2) (R_(1) gt R_(1))`. If the potential difference across the source having internal resistance `R_(2)` is zero, then

Two sources of equal emf are connected to an external resistance R. The internal resistance of the two sources are R_1 and R_2(R_1gtR_1). if the potential difference across the source having internal resistance R_2 is zero, then

Two sources of equal emf are connected to an external resistance R. The internal resistance of the two sources are R_1 and R_2(R_1gtR_1) . if the potential difference across the source having internal resistance R_2 is zero, then find vlaue of R.

If the potential difference across the internal resistance r_(1) is equal to the emf E of the battery, then

Two cells, having the same emf, are connected in series through an external resistance R . Cells have internal resistance r_(1) and r_(2) (r_(1) gt r_(2)) respectively. When the circuit is closed, the potential difference across the first cell is zero the value of R is

Two cells, having the same emf, are connected in series through an external resistance R. Cells have internal resistance r_(1) and r_(2) (r_(1) gt r_(2)) respectively. When the circuit is closed, the potentail difference across the first cell is zero the value of R shown in the figure
