Toisiokäämis

Toisiokäämis, often translated as secondary coil, is a fundamental component in transformer and induction coil designs. It refers to the coil of wire that is not directly connected to the alternating current (AC) power source in a transformer. Instead, the toisiokäämis receives its electrical energy through electromagnetic induction from the primary coil (ensisijainen käämis). The relationship between the number of turns in the toisiokäämis and the ensisijainen käämis determines the voltage transformation. If the toisiokäämis has more turns than the ensisijainen käämis, the voltage is stepped up. Conversely, if it has fewer turns, the voltage is stepped down. This principle is crucial for efficiently transmitting electricity over long distances at high voltages and then reducing it to safe levels for end-use. Induction coils, used in applications like ignition systems, also utilize a toisiokäämis to generate high-voltage pulses. The design and material of the toisiokäämis, including its wire gauge and insulation, are critical for its performance and efficiency in these electrical devices.
