Answer:
<em>Approximately 5 x 10^18 electrons are delivered to the smart phone charger.</em>
<em></em>
Explanation:
The electric current in a circuit is the flow of charges through a circuit with time.
The charges through the circuit are due to the electrons that flow through the circuit.
An individual electrons has a charge of -1.60 x 10^-19 C on it.
If the current through the circuit is -0.75 C/s, then the number of electrons that are delivered is gotten by dividing the charge per second by the charge on an electron.
==> -0.75/(-1.60 x 10^-19) = 4.67 x 10^18 electrons ≅ <em>5 x 10^18 electrons are delivered to the smart phone charger.</em>
