Power transfer by a non-ideal cell to an...

Power transfer by a non-ideal cell to an external resistor can be same for two different values. Out of which on value `(R_(1))` is less than internal resistance of cell and another `(R_(2))` is greater than internal resistance of cell then:

A

`R_(1)` will give less internal loss

B

`R_(1)` will give more battery life

C

`R_(2)` will give less efficiency

D

`R_(2)` will give more battery life

Text Solution

Verified by Experts

The correct Answer is:
D

Internal loss `=i^(2)r` whre `i=(epsilon)/(r+R)`
battery life time `=("Battery capacity")/("Curent")`

What maximum power can be obtained from a battery of emf epsilon and internal resistance r connected with an external resistance R ?

For a cell terminal potential difference is 2.2 V when circuit is open and reduces to 1.8V when cell is connected to a resistance of R= 5Omega then determine internal resistance of cell is:-

Assertion: Terminal potential difference of a cell is always less than its emf. Reason: Potential drop on internal resistance of cell increases terminal potential difference.
