Q1:

If a 24 V and a 6 V battery are series opposing, the total voltage is

A 30 V

B 24 V

C 18 V

D 0 V

ANS:C - 18 V

If a cell connects a series negative terminal of the cell a connected to a positive terminal of an another cell. By applying a sign conversion rule to this circuit you get an answer.
