FCC Exam Question: 6A59

The conductance (G) of a circuit if 6 A flows when 12 VDC is applied is:

A. 0.5 mho
B. 1.0 mho
C. 0.25 mho
D. None of the above
Correct Answer: A

Explanation: Conductance (G) is a measure of how easily current flows through a material. It is the reciprocal of resistance (R). In a DC circuit, it can be directly calculated using Ohm's Law principles. Given current (I) = 6 Amperes and voltage (V) = 12 Volts. The formula for conductance is G = I / V. Plugging in the values: G = 6 A / 12 V G = 0.5 Siemens (or mho) Therefore, the conductance is 0.5 mho. Option A is correct. Options B and C are incorrect as they do not result from the proper application of the formula with the given values.
