CBSE Class 12-science Answered
Why the light of a motor vehicle becomes dim when it is started?
Asked by Topperlearning User | 04 Jun, 2014, 01:23: PM
Expert Answer
On starting the vehicle initially, a large amount of current is draws from the battery. This causes a large voltage drop across the internal resistance of the battery. Consequently the potential difference across the terminals of battery also reduced. This potential drop across the terminal of the battery makes the light dim.
