Answer: d
Explanation: The number of rotor slots and the bar current along with the number of poles is calculated. On substitution it gives the end ring current value

The term “end ring current” could be interpreted in a few different ways depending on the context in which it’s used, as it’s not a standard term with a widely recognized definition in physics or electrical engineering. However, considering possible contexts, here are a couple of interpretations and explanations:
1. In the context of induction motors: An end ring current could refer to the current in the end rings of a squirrel-cage induction motor. These end rings connect the rotor bars at each end to form a closed loop, allowing the induction of current by the magnetic field from the stator. The specific formula for the current in these end rings would depend on the design of the motor, the load, and the applied voltage. However, a direct formula for the “end ring current” specifically isn’t typically provided in standard texts, as the focus is often on the overall performance characteristics of the motor rather than the specific currents in individual components.
2. In chemical or molecular contexts: The term could potentially refer to currents within cyclic molecules, such as those seen in aromatic rings where electrons are delocalized. This concept is a part of what is known as “ring current” effects in molecules like benzene. The ring current effect can explain the magnetic properties of the molecule and its chemical shift in NMR spectroscopy. However, the “formula” for this effect isn’t a simple equation but rather a consequence of the quantum-mechanical behavior of electrons in delocalized π systems.
