Question 1 1 pts What effect did adding a resistor to the series circuit have on the current through the circuit? The resistor protects the LED by slowing the current to a safe velocity. O The resistor lowered the voltage in the circuit, keeping the LED below the minimum forward voltage. O Resistors do not affect current because resistors are conductors. Resistors limit the total power through the LED, which keeps the LED safe from burning out. O The resistor limited the current through the circuit, preventing damage to the LED. Question 2 2 pts What evidence of the resistor's effect on current did you observe in the lab? With the 100 0 resistor in the circuit the LED lit up and did not burn out. When the resistance was increased to 10 kQ, the brightness of the LED was reduced. O A yellow LED was used instead of a green one. O None. The resistor limits voltage, not current, so the evidence observed was not relevant to current. O With the 10 ko resistor connected in the circuit, the LED at D1 lit brighter when SW1 was closed than it had with the 100 0 resistor in series.Question 3 2 pts What was the effect of changing the order of the components in the series? O Changing the order of the components in the series changed the brightness of the LED. O Changing the order of the components made no apparent difference to how the circuit worked. Conventional current means that when the resistor is placed between the LED and high potential, the resistor limits the current before it gets to the LED. When the resistor is placed between the LED and ground (negative), electron flow takes over and limits the amount of charges (electrons) before they get to the LED. O Changing the order of the components made no apparent difference to how the circuit worked. This is evidence that the resistor limits the current through the whole series. O Changing the order of the components in the series altered whether the LED lit before or after SW1 was closed
