ohms
question 7 (1 point)
(9.23_q7) electronic materials have resistance to the flow of electrons and it is measured in
amperes (amps)
current
voltage
ohms (ω)
question 8 (1 point)
(9.23_q8) a material which allows fewer electrons to travel through it has
high electrical resistance (high ohms, ω)
low electrical resistance (low ohms, ω)
question 9 (1 point)
(9.23_q9) the flow of electrons thru a wire is called electricity. the amount of electrons flowing through the wire is called
amperes (amps)
current
voltage
ohms
question 10 (1 point)
(9.23_q10) an electronic device meant to provide resistance to the flow of electrons is called a .
resistor
led
wire
question 11 (1 point)
(9.23_q11) which provides more resistance?
a 1 mω resistor
a 1 kω resistor
a 1 ω resistor
question 12 (1 point)
(9.23_q12) what happens if we hook up an led into a circuit in the wrong direction?
the led glows twice as bright as normal
the led glows half as bright as normal
the led glows normally, it makes no difference at all.
the led doesn’t glow at all
question 13 (1 point)
(9.23_q13) the correct formula for calculating the resistance needed to protect an electronic component from too much voltage is
component amps / forward voltage
power source voltage / component amps
(power source voltage - component forward voltage) / component amps

shorter
longer
right
left
question 15 (1 point)
(9.23_q15) when building a protype circuit in the real world, instead of clamping or soldering connections, we would use a
resistor
breadboard
light emitting diode

Aresearcher designed an investigation to test what effect eating different types of food would have on blood insulin levels. she selected 10 male subjects who were all 25 years of age and in good health. the experiment took place over 3 days. at 8: 00 a. m. on each day, the subjects ate a meal consisting of only 1 type of food. they had their blood insulin levels measured after consuming the meal. on day 1 they ate a high fat diet, on day 2 they ate a high protein diet, and on day 3 they ate a high sugar diel what is the independent variable in this experiment? a the age of the subjects b the blood insulin level c the type of food consumed d the time of day the meal was consumed
