How do I know how many amps my draws are?
You can usually find this information listed on the product label, or in the owner’s manual. Then you take the wattage, and divide it by the voltage (100 watts / 12 volts = 8.33 amps.) This will tell you roughly the amperage your equipment will draw.
How do you calculate the current flow in a series circuit?
Amperage (or Amps) in a Series Circuit The equation V = I/R, known as Ohm’s Law, also holds true at each resistor in the circuit. The current flow throughout a series circuit is constant, which means it’s the same at each resistor. You can calculate the voltage drop at each resistor using Ohms’ Law.
How to calculate maximum AC power input current?
Input Current = Maximum Power/(Efficiency)(Power Factor)(Minimum Input Voltage)(√3) These input current calculations are for the worst case: assuming the unit is running at maximum power, operating at a low line condition and taking efficiency and power factor into account.

How to calculate the maximum current of a resistor?
If you divide 8.366V by 140 ohms you get 59.76 mA which the maximum current the resistor can handle. How do you know this is the max current? well use P=V*I to check.
How to calculate total current ( with pictures )?
The easiest way to picture a series circuit connection is a chain of elements. The elements are added consequently and in the same line. There is only one path wherein the electrons and charges can flow. Once you have a basic idea of what a series circuit connection involves, you can learn how to calculate total current.
