Final answer:
Using Ohm's Law, the current flowing through parallel motor windings with a total resistance of 20Ω and an applied voltage of 280V is calculated to be 14 A.
Step-by-step explanation:
The question involves calculating the current flowing through a circuit with motor windings connected in parallel when a voltage of 280V is applied. To find the current, we use Ohm's Law, which states that the current (I) is the voltage (V) divided by the resistance (R). Because the total resistance is given as 20Ω, the current calculation would be I = V/R = 280V / 20Ω = 14A. Therefore, the correct answer is B) 14 A.
