Science Test (Electricity) Flashcards
please just pass, that's all I need.
what is electric current
the measure of how may electrons pass a point in the circuit in one second or the rate of the electron flow
what is current measured in
amperes (A)
how is it measured
using an ammeter
how must an ammeter be connected to a circuit
in series
0.016 is known as
the let go threshold
at 0.050 it will cause
ventricle fibrillation
what is electric resistance
the opposit to electric flow
what’s it measured in
ohms
four things that influence resistance
length of wire, temperature, thickness of the wire, and the conducting material
as current increases…. does too
voltage
if voltage remains constant and resistance increases the…. will….
the current will decrease
what does a parallel circuit have
multiple loads and provides more than one path on which electrons flow
what does a series circuit have
multiple loads and only one path on which electrons flow
voltage in series
v1 + v2 + v3 = total
voltage in parallel
v1 = v2 = v3 = total
