How to draw a circuit diagram showing two 4-volt lamps be lit brightly from two-volt cells?
Asked by Ravi Rekha | 28 May, 2011, 12:00: AM
answered-by-expert Expert Answer
To get a 4-volt lamp to light brightly, you need to supply it with 4V.
As we don't know the current rating of the individual lamps, but we do know that they want the same voltage, connect the two lamps in parallel.
Two 2V cells connected in series will supply 4V.
