Aim : Make a simulink model of Doorbell using solenoid block. Report: 1.In simulink Model of door bell using solenoid block,we need a switch,solenoid,battery and a plunger.                                2. Now first a 'solenoid block' is taken to represent a solenoid in the model, then to represent battery we have taken…

ANS 1 Difference between mapped and dynamic model of engine: Powertrain Blockset provides two types of Engine models: mapped and dynamic. Mapped engines represent macro engine behavior as a set of lookup tables (brake torque, fuel flow, air mass flow, exhaust temperature, efficiency and emissions) as a function of commanded…

ANS 1 CONCLUSION: Thus we can see that for 3 number of cycles at the given conditions, the vehicle can travel for only 41.1 km. * If we increse the number of cycles then the vehicle can travel above 45 km.   ANS 2 We can see that by increasing the battery capacity, the vehicle can travel for more than 53kms in the…

ANS 1 *Types of power converter circuits employed in an electric and HEVs- Power electronics is the application to control and conversion of electric power.
