This is not my homework but rather something that suddenly
occurred to me. batteries and bulbs are somethings i see often but
yet i dont seem to have complete knowledge of. please enlighten me
:)
say i connected 3 batteries in series to a bulb. the bulb lights
up. now i swap the polarity of one of the 3 batteries. what will
happen?
-the bulb becomes dimmer (due to the opposing current of the
reversed battery)
or
-the circuit will not light up at all (due to the reversed
battery blocking all the current)
next scenario
I connected 2 batteries in series and another battery in
parallel but in the opposing direction to a bulb. what will
happen?
-the bulb becomes dimmer (due to the opposing current of the
reversed battery)
or
-the circuit will not light up at all (due to the reversed
battery blocking all the current)
or
-no effect at all. the bulb will shine as if there isnt any
battery connected in parallel.
