PHYSICAL SCIENCE FINAL EXAM QUESTIONS WITH COMPLETE
SOLUTIONS VERIFIED GRADED A+
Electric Current
The rate of charge flow, measured in Coulombs per second (C/s), also known as
Amperes (A).
-The current is opposite of the flow of electrons
2 Primary Requirements of an Electric Circuit
1. Voltage Source
2. Circuit [low to high voltage (closed loop)]
Circuit Diagram
-Graphical Representation of an electrical circuit, illustrates the path of desired electrical
circuit
Series Circuit
An electric circuit connected so that charges move in "series" first going to one resistor
then the next
-In a series circuit, the current through each of the components is the same, and the
voltage across the circuit is the sum of the voltages across each component.
-In a series circuit, every device must function for the circuit to be complete. One bulb
burning out in a series circuit breaks the circuit
, Parallel Circuit
A circuit composed of two (or more) components connected in parallel.
-In a parallel circuit, the voltage across each of the components is the same, and the
total current is the sum of the currents through each component
-In parallel circuits, each light has its own circuit, so all but one light could be burned
out, and the last one will still function.
-Parallel circuits (generally) are much brighter
-Current increases with each additional pathway
Which type of circuit has brighter bulbs?
Parallel
Which type of circuit requires the most current flow through the battery?
Parallel
If two bulbs are in series, what can you say about the current flow through them?
The current flowing through them is the same
The Junction Rule
The sum of the all currents flowing in to a junction is equal to the sum all currents
flowing out of the junction, based on the Conservation of Charge
-Applies to a current at a junction of 3 or more wires
Formula: Ia= Ib + Ic
Direction of Current Flow in Parallel Circuits
