A tetrad field with spherical symmetry is applied to the charged field equations of f(T) gravity theory. A special spherically symmetric charged-dS solution is obtained. The scalar torsion of this solution is a vanishing quantity. The spacetime of the derived solution is rewritten as a multiplication of three matrices: The first matrix is a special case of Euler's angle "so(3)," the second matrix represents a boost transformation, while the third matrix is the square root of the spherically symmetric charged-dS metric. It is shown that the boost matrix is important because it plays an essential role in adjusting the spacetime to become a solution for f(T) theory. © 2013 American Physical Society.
