The formula for amperage is I = W/E. Amps = Watts/Volts. As you can see there are two values missing from the question.

Depends on your light usually it's a 60 wat balb
Almost any average size home today will requre a 200 amp service panel.
depends greatly on size usually assessed in tonnage how old the unit is and more
Depending on size of Fridge. But AVERAGE is 12 volts for fridge, circuit necessity 15 amps 15 amps X 120 Volts=1800 watts minimum...I'm LEARNING myself
Depends on what refrigerator you are interested in. They all have a label somewhere, usually in the refrigerator compartment that lists the current. My refrigerator has a rating of 11.6 Amps. This is not a consistent current, but would be when the compressor is running.
1 AMP
How many Amps is the fridge pulling? Multiply the Amps by the 120V circuit you're plugging into and you'll get your Watts.
To convert amps into watts a voltage is needed. Watts = Amps x Volts.
300kva equals zero amps. Voltage is needed to answer this question.
You cannot increase voltage by adding amps.
If you are talking about a certain kind or brand, look at the label inside the door. The label will tell you how many amps this unit will need. However all residential refrigerators will run on a 15 amp dedicated circuit or be fine plugged into a regular 20 amp appliance circuit (which is required in kitchens). I have a large side by side unit and it only draws 6.6 amps max. Note that the starting current of an induction motor will be higher, of course, but will drop and stabilize at a "nominal" level within seconds.
