of
ent
What is the overall voltage with this
arrangement?
(A) OV
(B) 4.5V
(C) 6.0V (D) 7.5V
​

Answer 1

Answer:

B) 4.5

Explanation:

since one is in opp direction

4×1.5-1×1.5=6-1.5=4.5

B) 4.5

Answer 2

Answer:

4.5 V

Explanation:

4 cells are in same direction so voltage = 4*1.5

1 cell in opposit direction so voltage = 1*1.5

total voltage = voltage in same direction- voltage in opposite direction

=4*1.5 - 1*1.5

= 1.5(4-1)

=1.5 (3)

=4.5
