A 3 φ I.M. has synchronous speed of 250rpm and 4% slip at full load. The rotor has a resistance of 0.02Ω/ph and stand still reactance of 0.15Ω/ph. Calculate i) The speed at which max torque is developed. ii) The ratio of maximum to F. L. torque. iii) The ratio of maximum to starting torque.
What is the N+ L rule?
What is the n and L in quantum numbers?
What is the n/l rule?
What is the L and N in AC? Answer : In an alternating current (AC) electrical system, **L** and **N** stand for **Live (or Line)** and **Neutral**. Here's a simple explanation: - **L (Live or Line)**: This is ... the one that carries the electrical potential, while the **Neutral** wire provides a path for the current to flow back....
How does a MOSFET's aspect ratio (W/L) affect its current-carrying capacity?
For zero initial conditions, write the equation for current in a series R-L circuit for step response.
Why is inductance represented by L, why not I?

Derive the expression for resonance frequency in R-L-C series circuit.
What is the SI unit of magnetic field?
What is SI unit of density?
What is V in SI unit of mobility?
What is the SI unit of AC conductivity? Answer : The SI unit of AC (alternating current) conductivity is the **siemens per meter (S/m)**. Conductivity is a measure of a material's ability to conduct electric current, and since it's the reciprocal of ... length of the material. So, in short, the SI unit of AC conductivity is **S/m**....

What is the SI unit of moving coil galvanometer? Answer : The SI unit of a moving coil galvanometer is the **ampere (A)**, since a moving coil galvanometer is primarily used to measure electric current. The instrument itself doesn't have a specific ... the readings from the galvanometer are typically in amperes, which is the SI unit of electric current....
What is the SI unit of voltage sensitivity?
What is the SI unit of galvanometer constant?
What is the SI unit of deflection of galvanometer? Answer : The SI unit of deflection of a galvanometer is not directly defined, as deflection is a *dimensionless* quantity. It's usually measured in terms of an angular displacement, which is typically expressed ... displacement (radians)** or **scale divisions**, depending on the design of the galvanometer....
