Current describes the rate of electricity (how fast charges are moving). Its formula is I = . The higher the current, the more charges are flowing per unit time. When charging smartphones using a standard USB port, only between 0.5 to 1.5 amps of current can be delivered.

Current describes the rate of electricity (how fast charges are moving). Its formula is I=q/t. The higher the current, the more charges are flowing per unit time. When charging smartphones using a standard USB port, only between 0.5 to 1.5 amps of current can be delivered. Dedicated chargers or superchargers can deliver higher currents, around 2.0 amps or more. Using a supercharger that can deliver 2.0 amps, how much charge is delivered in 1 hour to a smartphone? Select: (7200C, 1800C, 3600C, or 120C) How many electrons is this? Select: (about 4.5E22 electrons, about 1.1E22 electrons, about 2.2E22 electrons, or about 9.9E22 electrons) If the supercharger has a voltage of 5V, what is the equivalent resistance of the smartphone? Select: (5 ohm, 10 ohm, 2.5 ohm, or 0.25 ohm) How much power (in Joules) was dissipated by the supercharger? Select: (5 Watts, 10 Watts, 20 Watts, or 25 Watts) What is this power in horsepower? Select: (0.0134 hp, 0.0537 hp, 0.0268 hp, or 0.0067 hp) How much energy was gained by the smartphone at the end of the 1 hour of charging?
