Explain the effect of variable excitation on the behaviour of synchronous motor under constant load condition.
There are a Transformer and an induction machine. Those two have the same supply. For which device the load current will be maximum? And why?
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 value of maximum power transfer from source to load?
Explain the concept of the following terms: (i) Connected load (ii) Maximum demand
An industrial consumer charged with the scheduled tariff of Rs.250 /kVA per month for maximum demand and 150 paisa per unit consumed for load factor of 60% and 80%. Find overall cost per unit at i) unity P.F. ii) 0.9 P.F. consider maximum demand of 50 kVA.
Make use of load factor and maximum demand tariff to minimize electrical consumption of electrical installation.

What will happen if a lead acid battery is kept in discharged condition for a long time? Answer : If a lead-acid battery is kept in a discharged state for a long time, several things can happen that can damage the battery permanently: 1. **Sulfation**: When a lead-acid battery is ... try to charge it fully and then maintain it with periodic charging to keep the battery in good condition....
Under what condition the terminal potential difference across a battery and it's emf are equal?
Under what condition the terminal potential difference across a battery and emf are equal? Answer : The terminal potential difference across a battery and its electromotive force (emf) are equal when **no current is flowing through the battery**. This happens when the battery is **open-circuited**, ... a voltage drop, and the terminal potential difference will be less than the emf of the battery....
