abstract={A modern Tesla coil is an excellent multidisciplinary example in undergraduate STEM teaching. It incorporates several concepts from physics and electrical engineering. For example, Ampere¡¯s law and Faraday¡¯s law are concepts in physics while an <i>LC</i> circuit, an <i>RLC</i> circuit, and the properties of a transistor are concepts in electrical engineering. A Tesla coil shows the intimate relationship between electricity and magnetism. Ampere¡¯s law states that a current induces a magnetic field and Faraday¡¯s law states that a changing magnetic flux induces a voltage. In a classical Tesla coil, a spark gap switches the current on and off flowing through the primary coil. Meanwhile, in many modern Tesla coils, a transistor is used instead of a spark gap, since it can switch on and off very quickly using a lower voltage. Several papers described how modern tesla coils work. However, the designs of modern Tesla coils were complicated and the mathematical descriptions for Tesla coils were beyond undergraduate students¡¯ level. This paper describes a modern Tesla coil by providing mathematical details that are appropriate for undergraduate students¡¯ level. To satisfy the educational purpose of this paper, we also choose the simplest design for a modern Tesla coil. The primary circuit in a modern Tesla coil used here is a parallel <i>RLC</i> circuit. We show that it can play the same role as the series <i>RLC</i> circuit of the primary circuit in the classical Tesla coil.},
