It sounds like your stove is missing a ground wire. Sounds like one of your elements has shorted to ground. Shut the stove off at the breaker and get a qualified electrician to look at the problem. For you to get a shock you must have had your other hand on the stove or you are standing on a grounded medium. (eg concrete floor.) DO NOT USE THE STOVE. The amount of current you could receive could kill you.

What is the wire that gives off light in a light bulb?

If they're not CO/ALR outlets, there is.
Is 5.0mA the same as half an amp?
"mA" represents "milliamp" so 5.0 mA would be 0.005 Amps, which is not half an amp (0.5 A) Milli means one thousandth so 500mA would be half an amp.
How many eletrcal outlets can you have in a garage?
There is no limit as to the amount of circuits you can have in a garage. If you mean how many devices on a 15 amp single circuit breaker then the answer is 12. Be sure to total in light fixture outlets and switch boxes.
Is THWN wire used for dry locations only?
No. Per the National Electrical Code, table 310.13, THWN is suitable for dry and wet locations with a maximum operating temperature of 75o C. THWN-2 wire is suitable for dry and wet locations up to 90o C.
BODMAS is a mnenomic for helping remember the order for dealing with mathematical operators in a mathematic statement.
First - brackets, then order (powers), then division, multiplication, addition and finally subtraction.
Resolving an equation following this will give a different result than a random order. e.g. 3x1+4(8/2)=19 not 60 nor 28 nor anything else.
What is the hourly rate for contractors?

Gauge wire needed for 8 amp sump pump?
you will need wiring that is at least 10 amp rated wire or higher. If you really needed to ask you might want to call an electrician Electrician here, be the pump 120 volts or 240 volts a #14 wire will handle the situation. Longer runs of 75 feet you should go to a #12 wire to compensate for voltage drop. The pump should be on its own separate circuit with a 15 amp breaker. A two pole 15 amp breaker if the pump is 240 volts.
voltage is measured by voltagd drops. When a switch is open/ off there is a voltage difference between one side to the other. when the switch is on there is no drop from one side of the switch to the other. That is normal operation. If switch is on, and you get a voltage reading across the switch, the switch is bad.
