We have two noise generators: one gives 3 the other 4 V effective voltage. We form a new generator by connecting them in serial arrangement. Then the resultant voltage is 7V. How will this voltage change

Answer:

The correct answer is -1

Step-by-step explanation:

As it has been mentioned that the generators are connected in serial arrangement so tha resultant voltage is +3V+4V=7V.Later it is mentioned that the polarity of 4V generator has been reversed which means -4V+3V= -1V

Hence the resultant voltage is -1.
