What is the name of the integrated circult that provides the initial run instructions when the computer is first booted?

Boot ROM. Most modern home computers use a type of FLASH EPROM for this to allow patches to fix bugs.

Why are circult breakers preferable to fuses?
It's not safer, but it is more convenient.
Why the transistor is not used in switching 'AC voltage'?
The transistor is a "single direction current flow" device. Typically, for an NPN device, the collector must be more positive than the emitter for the device to bias on. You could use the transistor in an AC circult, but it would only conduct on half the cycle.
What happens when you add more light bulbs in a parallel circuit?
it doesn't, in a parallel circult the volage stays the same therefore the brightness will stay the same
How does the loading effect of a voltmeter in a high-rsistance circuit compare to the loading effect in a low-resistance circult?
The voltmeter has an internal resistance, which should be as high as possible. As this resistance draws current from the circuit under test, it will affect circuit operation. This is more pronounced in a high impedance circuit because the current drawn flows through higher resistances.
