Question 1 of 5
What is the primary function of a resistor in an electronic circuit?
A resistor's primary function is to limit or resist the flow of current.
Question 2 of 5
What is the unit of measurement for electrical resistance?
Resistance is measured in Ohms (?).
Question 3 of 5
According to Ohm's Law, what is the formula for calculating resistance (R)?
Ohm's Law states R = V / I, where V is voltage and I is current.
Question 4 of 5
In the resistor color code, what does the first two bands typically represent?
The first two bands represent the significant digits of the resistor value.
Question 5 of 5
If a resistor has the color bands yellow, blue, orange, and silver, what is its approximate resistance value?
Yellow (4), Blue (6), Orange (x1000), Silver (±10%) = 46 k? ± 10%
