60 Hz

60 Hz refers to the frequency at which an alternating electrical current or signal oscillates, completing 60 cycles per second. In everyday electronics, such as household power in many countries (like the United States), the electrical supply alternates its direction 60 times each second. This frequency impacts the operation of devices like televisions and oscilloscopes, ensuring they function correctly and synchronize with the power supply. Essentially, 60 Hz indicates the speed of change in the electrical current's direction, contributing to stable power delivery and proper device performance.
