Question

question 16 (1 point)
electrons possess potential energy. in a circuit, this potential energy may be transformed into
a. heat energy d. any of the above
b. light energy e. none of the above
c. motion
question 17 (1 point)
which of the following statements describes the correct way to measure the resistance of a load with an ohmmeter?
a. in series with the load while the circuit is connected
b. in series with the load while the circuit is disconnected
c. in parallel with the load while the circuit is connected
d. in parallel with the load while the circuit is disconnected

Explanation:

Question 16

In a circuit, electrons' potential energy (from voltage) can transform into heat (e.g., in resistors), light (e.g., in bulbs), or motion (e.g., in motors). So it can be any of these, making option d correct.

An ohmmeter measures resistance by applying a small voltage. To measure a load's resistance, the load must be disconnected from the circuit (to avoid other voltage sources) and the ohmmeter is connected in series with the load (as it measures the current through the load for resistance calculation \( R=\frac{V}{I} \)). So option b is correct.

Answer:

d. any of the above
