The most general form of the weak hadronic current in the colored quark model is analyzed under the assumption that the algebra of weak charges is closed. A direct consequence of this assumption is the absence of off-diagonal neutral currents. The nonvanishing components of the neutral current are identical to the components of the electric charge. This makes it possible to construct the electromagnetic current as a sum of left-handed and right-handed weak currents. The general expression for the current obtained in this manner depends on eight parameters; however, most of the known physical requirements can be satisfied by using two angles analogous to the Cabibbo angle. If one requires that exotic transitions be forbidden, one can obtain a value sintheta/sub C/=0.211 for the Cabibbo angle. A method of construction of currents is indicated which can be applied to any theory with a symmetry of the color type.
