60 Watts is the amount of electrical power the bulb uses when it is switched on.
Yes if it is a 12 volt DC bulb.
If you used them simultaneously, probably around 1.46 million 60Watt bulbs.
In a typical residential 60 Watt incandescent bulb, the resistance of the filament is what dictates the current flow given a household voltage of 120 VAC the current is 1/2 amp. By Ohm's Law that means the resistance is 240 Ohms. In your example, a 60 Watt bulb at 30 Volts drawing 2 Amps would have a resistance of 15 Ohms. If you change the voltage to 15 Volts the resistance will still be 15 Ohms and current will be V/R = 1 Amp. The bulb, if it lit at all would be less than 1/2 as bright as the 30 Volt situation.

Yes you can.
Power = Current * Voltage Current = Power / Voltage Current = 60 W / 120 V Curretn = 0.5 A
About as much as 15 typical (60watt each) light bulbs together. Or expressed in horsepower: about 1.2Hp Mains volts and ampere: 230 volt at 3.91 ampere = 900watt 110 volt at 8.18 ampere = 900watt
B - Dynamic resistance
The different types of resistance available on exercise bikes are magnetic resistance, air resistance, and friction resistance. Magnetic resistance uses magnets to create resistance, air resistance uses air to create resistance, and friction resistance uses a brake pad to create resistance.
Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.
abrasion resistance is the resistance in abrasion
