Question 3-18B6
Element 3 (GROL)What is the conductance (G) of a circuit if 6 amperes of current flows when 12 volts DC is applied?
Explanation
Conductance (G) is a fundamental property in electrical circuits, representing how easily current flows through a material. It is the reciprocal of resistance (R). Ohm's Law, which states V = I * R, can be rearranged to include conductance.
Since G = 1/R, we can substitute R = 1/G into Ohm's Law:
V = I * (1/G)
V = I / G
Rearranging to solve for conductance (G):
G = I / V
Given:
Current (I) = 6 amperes
Voltage (V) = 12 volts
Calculation:
G = 6 A / 12 V
G = 0.5 Siemens (or mhos)
Therefore, the conductance is 0.5 Siemens. The other options are incorrect as they do not result from the correct application of the formula relating current, voltage, and conductance.
