  We wish to construct a model for charged star as a generalization of the
uniform density Schwarzschild interior solution. We employ the Vaidya and
Tikekar ansatz [{\it Astrophys. Astron.} {\bf 3} (1982) 325] for one of the
metric potentials and electric field is chosen in such a way that when it is
switched off the metric reduces to the Schwarzschild. This relates charge
distribution to the Vaidya-Tikekar parameter, $k$, indicating deviation form
sphericity of three dimensional space when embedded into four dimensional
Euclidean space. The model is examined against all the physical conditions
required for a relativistic charged fluid sphere as an interior to a charged
star. We also obtain and discuss charged analogue of the Buchdahl compactness
bound.
