IAHCSMM CER Chapters 9&10 Exam 2025 With Complete
Questions And All Correct Answers Newest Update A+ Graded
And Passed
what ways do electrons flow in the circuit - CORRECT ANSWER electrons flow in a
counterclockwise direction from the negative terminal of the electric cell, through the
bulb, and back to the positive terminal.
electric current - CORRECT ANSWER the flow of electric charges
Ampere (A) - CORRECT ANSWER unit of measurement for electric current
André Marie Ampère - CORRECT ANSWER a French physicist that ampere is named
after
formula for calculating current - CORRECT ANSWER I= Q/ t
electric shock - CORRECT ANSWER if you touch a complete circuit, with a source of
electricity,
conventional current - CORRECT ANSWER The direction that a positive charge would
take in a circuit.
electron flow - CORRECT ANSWER opposite to the direction of conventional current
direct current (dc) - CORRECT ANSWER The electric current supplied from an electric
cell flows in a single direction
examples of direct current - CORRECT ANSWER Battery-operated watches and
devices
alternant current - CORRECT ANSWER Alternating current results when the electrons
periodically reverse direction.
series circuit - CORRECT ANSWER Circuits, or devices within a circuit, can be
connected in series or in parallel. When devices, such as light bulbs, are connected in a
series circuit, the current goes through each device in sequence
parallel circuit - CORRECT ANSWER When devices are connected in a parallel circuit,
the current splits up and some of the current goes through
each device
, ammeters - CORRECT ANSWER used to measure the amount of electric current at a
point in a circuit.
how does the ammeters work? - CORRECT ANSWER it is connected directly to the
path of the moving electric charges
mustimeter - CORRECT ANSWER measures current, and also measures other
electrical quantities.
voltage - CORRECT ANSWER the electric potential difference
formula for voltage - CORRECT ANSWER V=delta / Q
voltmeter - CORRECT ANSWER device that measures the electric potential difference,
or voltage.
how voltmeters work - CORRECT ANSWER When you connect a voltmeter to the
positive and negative terminals of a battery, the voltmeter measures the difference in
volts between the positive and negative terminals
static charge - CORRECT ANSWER an imbalance of electric charges within or on the
surface of a material. The charge remains until it is able to move away by means of an
electric current or electrical discharge.
Discharge - CORRECT ANSWER when a charge moves from the original object and
transfers to another object
electrostatics - CORRECT ANSWER The study of static electricity charge
Benjamin Franklin 's Experiment - CORRECT ANSWER He proved that lighting is a
form of electricity by flying a silk kite during a thunderstorm with a key tied onto a ribbon
he was holding. The storm struck the kite and sent an electric charge into the key but
stayed there as the ribbon could not transfer the electric charge, he got a shock form
the key, but not the ribbon,
Conclusion of Benjamin Franklin 's experiment - CORRECT ANSWER He proved that
lighting is a form of electricity and that there are positive and negative charges
Can we see electrostatic charges? - CORRECT ANSWER No we can't but we can see
the effects, example - lighting
Positive charge - CORRECT ANSWER this electric charge happens when an object
loses electrons, making them have more protons than electrons, this is represented by
the plus sign (+)
