Question

what affects electrical resistance? a. thickness of wire b. length of wire c. type of wire d. temperature of wire e. all of the above. question 5 the d in coulombs law equation stands for the _____. a. mass of a charged object. b. number of excess electrons on the object. c. the current of a charged object. d. the distance between the charged objects. e. charge of the object. question 6 which is a flow of electric charge? 1. voltage. 2. electric current. 3. both a and b. 4. neither a nor b.

Explanation:

• For the first question, electrical resistance is affected by the thickness (inversely related, thicker wire has lower resistance), length (directly - related, longer wire has higher resistance), type of material (different materials have different resistivities), and temperature (for most conductors, resistance increases with temperature).
• For the second question, Coulomb's law is $F = k\frac{q_1q_2}{d^2}$, where $d$ is the distance between the charged objects.
• For the third question, electric current is defined as the flow of electric charge. Voltage is the electric potential difference that causes the charge to flow.

Answer:

• Question 1: E. All of the above
• Question 5: D. the distance between the charged objects
• Question 6: 2. Electric current
