5 Questions
Question 1 of 5
What is the unit of measurement for electrical resistance?
Resistance is measured in Ohms, named after Georg Ohm.
Question 2 of 5
According to Ohm's Law, what is the relationship between voltage (V), current (I), and resistance (R)?
Ohm's Law states that Voltage equals Current times Resistance.
Question 3 of 5
Which of the following materials generally has the highest electrical resistance?
Rubber is an insulator and offers very high resistance to current flow.
Question 4 of 5
What happens to the resistance of a wire if its length is doubled (assuming the cross-sectional area and material remain constant)?
Resistance is directly proportional to the length of the wire.
Question 5 of 5
If two resistors are connected in series, how is the total resistance calculated?
In series, the resistances simply add up to give the total resistance.
