该小组的设备是一个电容和一个与其连接的感应线圈。
The team's set-up consisted of an inducting coil connected to a capacitor.
电容产生电场，线圈生成磁场，电路中的能量就在电场和磁场之间高速振荡。
The energy within this circuit oscillates rapidly between an electric field in the capacitor and a magnetic field in the coil.
振荡频率由电容储存电荷的能力，以及线圈生成磁场的能力所共同决定。
The frequency of this oscillation is controlled by the capacitor's ability to store charge and the coil's ability to produce a magnetic field.
