$1.75V$

Voltage can be defined as the amount of energy lost or gained by a unit charge as it moves across a circuit from one point to another.

This means $"voltage" = "energy lost by charge"/"charge moving"$
The charge we are considering in this case is $4C$

The amount of energy lost is $(22-15)J=7J$

Thus the voltage is $7/4V= color(blue)(1.75V)$
