In series combination of resistances —

1. p.d. is same across each resistance
2. total resistance is reduced
3. current is same in each resistance
4. all of the above are true

For parallel combination of resistances, which of the statements are correct ?

1. On I-V graph, the slope of line is more.
2. The potential difference across each resistance is same.
3. The current in a resistor is inversely proportional to the resistance.
4. All of the above

Assertion (A): The terminal voltage of a cell is always less than its e.m.f.

Reason (R): More the current drawn from the cell, the less is the terminal voltage.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true and R is not the correct explanation of A.
3. assertion is false but reason is true.
4. assertion is true but reason is false.
