Question

which of the following equipment is used to test for voltage drops and high resistance within the primary circuit?

a. spark testers
b. led test light
c. digital multimeter
d. standard test light

Explanation:

A digital multimeter can measure voltage (to detect voltage drops) and resistance (to identify high resistance). Spark testers check for spark in ignition systems. LED and standard test lights mainly indicate presence of voltage but are less precise for measuring voltage drops and resistance values.

Answer:

C. Digital multimeter
