Consider the resistive circuit shown in the figure. The battery has negligible internal resistance.
All the resistors are identical. An additional identical resistor is connected between points E and G.
3. The current at point A
(a) increases
(b) decreases
(c) stays the same
4. The potential difference between points E and F
(a) increases
(b) decreases
(c) stays the same
Return to the initial condition shown in the figure. Another identical resistor is connected between points C and B.
5. The current at point D
(a) increases
(b) decreases
(c) stays the same.
6. The potential difference between points A and C
(a) increases
(b) decreases
(c) stays the same.
Explanation / Answer
3. Current at point A will increase because net resistance of the circuit will decrease. 4.Since the R between E and F is same and current decrases, hence V= IR also decreases 5.Decrease 6.Decrease
