Vocabulary
circuit - a closed loop through which electrical charges can continuously flow. current (I) - the flow of electric charge per unit time; SI unit is the ampere (A). electric potential (V) - also known as voltage, the energy capacity of a unit of charge; the SI unit is the volt (V). Ohm’s Law - law formulated by Georg Ohm that relates current, voltage, and resistance within a circuit; voltage is equal to current times resistance. resistance (R) - the opposition of a material to the flow of electric current; the SI unit is the ohm (Ω). |
