Parts of a Current
Source of power • Device • Conductor connecting all parts
Voltage
Adding bad - decrease voltage
Movement
Electrons move from - terminal to * terminal
Circuit symbols
cell-D -11- A device that converts chemical energy into electrical
Battery
multiple cells in combination
Connecting wire
conductor
Sub/load
light bulb
Current flow
switch → Topens or cart
Voltmeter
measure voltage
Ammeter
measure current
Motor
convert electrical to mechanical energy
Fuse
break excessive current
Series circuits
All loads must be on and working at the same time
Pros of Series
Has wires lower cost
Parallel circuits
Two or more paths for current to follow
Charge
Amount of Electricity
Charge measures
Coulombs (C) a=6.15 x 10^18 electrons
Q = C
I = Amperes
t = time in seconds
Calculating
V = IR
v = voltage (power)
(v)
I = current (Amperes)
(A)
R = resistance (Ohm)
(Ω)
