Parallel combination of cells

When positive terminals of every cell are connected together and negative cells are connected together in a cell, then we call the cells as parallel cells. ... If the emf of the individual cells is similar, then emf of the battery which is connected by n cells in parallel will be equal to the emf of each individual cell.
