What were used before transistors?
If the integrated circuit in some kind of device has 5,000 transistors on it, then before integrated circuits were available, the same function might have been performed by 100 individual transistors. And before transistors were available, the same function might have been performed by 30 vacuum tubes, a fan and air system to keep them cool, and a large power system to operate the tubes and the cooler.
What property would you be testing for if you are using a circuit breaker?
A circuit breaker is not a test instrument, it is a kind of switch that interrupts the supply when that is needed, but it is more than that because circuit breakers are specialised items, and examples exist that can interrupt currents of hundreds or thousands of amps at very high voltage.
