Adding on to Unit 11, we dug further and learned more about electricity. I learned that current is the number of charges passing a point per second, or the rate of flow of charges. Current can be represented by the variable "I" and is measured in Amperes or Amps. One Amp (A) is equal to 1 Coulomb per second (I = q/t). Recapping from last week, voltage is the amount of work that each charge will do as it goes through the circuit; it can be thought of as the amount of "push" on the charge. So voltage is the amount of energy per charge and current is the amount of charge per second. A great example of this are these ceiling lights. Electrons (charges) are carrying energy (joules) and are passing through the lightbulb. As each electron passes through the bulb, it drops off and supplies a constant flow of energy, allowing the bulbs to stay lit.
