Unit 7 Electricity by Anthony Cerqua https://padlet.com/anthony_cerqua/ip1z25i03u2z Concept map for Unit 7 en-us 2018-04-11 13:50:51 UTC 2025-12-16 13:33:50 UTC hello@padlet.com Electricity anthony_cerqua https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250711386 Physical phenomena associated with the presence and flow of electrons]]> 2018-04-11 13:52:28 UTC https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250711386 What do we need to light a lightbulb? anthony_cerqua https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250711925 1. Power source (battery): Provides push for electrons
2. Closed loop or "continuous conducting path": Full loop for electrons to move from negative to positive side of battery]]> 2018-04-11 13:53:19 UTC https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250711925 Water Analogy anthony_cerqua https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250712905 Voltage = Push (battery/water pump)
Current = Amount of flow (water/electrons)
Resistance: Limits flow of electrons]]> 2018-04-11 13:54:50 UTC https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250712905 Voltage anthony_cerqua https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250713892 "Push" of the circuit
Comes from battery separating charge
"Source" provides voltage (ex: battery)
"Load" uses voltage (ex: lightbulb, computer, etc.)
Symbol: V
Unit: Volts (V)]]> 2018-04-11 13:56:28 UTC https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250713892 Current anthony_cerqua https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250714558 Amount of flow of electrons
Equation: I = Q/t
Symbol: I
Units: Coulombs/second = 1 A (Ampere)]]> 2018-04-11 13:57:31 UTC https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250714558 Resistance anthony_cerqua https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250715769 Limits the flow of electrons
Symbol: R
Units: Ohms]]> 2018-04-11 13:59:39 UTC https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/250715769 Ohm's Law anthony_cerqua https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/349674364 -Current is directly proportional to voltage
-Current is inversely proportional to resistance

I = V/R]]> 2019-04-08 18:58:06 UTC https://padlet.com/anthony_cerqua/ip1z25i03u2z/wish/349674364
