The maximum amperage rating for a 200 amp main disconnect in an electrical panel is 200 amps.
The maximum amperage capacity of a 100 amp main breaker in an electrical panel is 100 amps.
The maximum amperage capacity of a 150 amp main breaker in an electrical panel is 150 amps.
I don’t know
I am looking for a position as an electrician technician, specifically focusing on residential and commercial electrical installation, maintenance, and repair. Ideally, I want a role that allows me to apply my technical skills in troubleshooting electrical systems and ensuring compliance with safety standards. I'm also interested in opportunities that provide professional development and growth within the electrical trade.
The new resistance will draw an additional branch current, resulting in an increase in the supply current. Another way of looking at it is, when you add additional resistance, the overall resistance will reduce, increasing the value of the supply current.
It depends on what part of California you are specifically looking for.

If the battery is dead you will need a battery charger. If the battery is good and you have low amperage then you will need another alternator. Most parts stores will check it for you. If you are looking for MORE amperage then you would have to buy a larger amperage alternator.
The formula you are looking for is I = sq root of W/R.
The amperage in the circuit can be calculated using Ohm's Law: Amperage = Voltage / Resistance. Plugging in the values, we get Amperage = 110V / 7ohms = 15.71A. Therefore, the circuit would have approximately 15.71 amps of current flowing through it.
When a fuse is blown, you can tell by looking for signs such as a darkened or melted appearance, a broken wire inside, or a lack of continuity when tested with a multimeter. Other signs include loss of power to certain electrical components or devices, flickering lights, or a burning smell. If you suspect a blown fuse, it is important to replace it with the correct type and amperage to ensure safety and proper functioning of the electrical system.
Generally speaking, you need to account for any variance in electrical output. There are a lot of factors that can cause a fluctuation in electrical amperage. You wouldn't want to set the fuse too low or it would blow needlessly, but you also don't want to set the fuse too high, or a dangerous short will not be interrupted. A power source/device can produce/draw more amperage while damaged than in normal operation. A 4.33 amp device might not run at 5 amp while working, but while damaged could exceed that dramatically. When looking at the reason for having a fuse, it provides two things: 1) help protect a working device from having too much amperage forced into it from a damaged power source 2) help protect the power source from having too much amperage draw from it by a damaged device.
