Voltage and Current - Technical MCQs

Q1:

In practical applications, battery voltage:

A is restored as soon as disconnect occurs

B is lowered as the load increases

C may be stored indefinitely

D will be reduced to zero as power is drawn

ANS:B - is lowered as the load increases

The battery is already charged now when the load is connected it is in discharging mode. So when load increases (here load increases means a device that we connected is drawing more current from source) voltage will come down gradually. So it is not like R increases I decreases so V decreases. One important thing is load resistance increases means are increasing. But load increasing means the current that is drawing by the device is increasing.
