The equivalent voltage is $= 4 V$ $=4V$

Explanation:

The batteries are in series, but the third one is reversed

The voltage of each battery is $E = 2 V$ $E=2V$

Therefore,

The voltage of the combination is

$E_{c} = 3 E - E = 3 \cdot 2 - 2 = 6 - 2 = 4 V$ $E_c=3E- E=3*2-2=6-2=4V$

$\Rightarrow 4 V$ $=>4"V"$

Explanation:

There is $2 V$ $2 "V"$ across each battery.

For combination circuits, you simply compute a weighted sum, where the directionality of each battery gives it a positive or negative value.

If we take left-to-right $(-) \to (+)$ $(-) -> (+)$ to be the positive configuration, then left-to-right $(+) \to (-)$ $(+)->(-)$ will be the negative configuration.

With the combination given, the first battery is $+ 2 V$ $+2"V"$ . The second battery is $+ 2 V$ $+2"V"$ . The third battery is $- 2 V$ $-2"V"$ . The fourth battery is $+ 2 V$ $+2"V"$ .

Summing:

$2 + 2 - 2 + 2 = 6 - 2 = 4 V$ $2+2-2+2 = 6-2 = 4"V"$

Hence the equivalent potential difference is $4 V$ $4"V"$ .
