Question 26 of 36 > >> Question 26 10 points Save Answer A water turbine in a hydroelectric dam is providing a constant 1 kW of mechanical power to an electric generator. There are several losses in the electromechanical system. It is found the electrical losses (L ) represents 26 % of the total losses in the electromechanical elec system. Electrical losses occur in the two components of the system where there is current flow: the rotor and the stator. Current flow in the rotor is constant* at 8 A and current flow in the stator is constant* at 3 A. The rotor has an electrical resistance of 1 Q and the stator has an electrical resistance of 4 0. How much electrical power is extracted from the electric generator? Give your answer as a positive value in Watts, to 0 decimal places. *NB: this is a simplification of a real-world electric generator, where you would expect current flow to be variable.

Question 25 10 points Save Answer The circuit below shows a transformer. The primary winding (Windingp) has 27 turns and is connected to an AC voltage source where the maximum potential difference across it is 22 V. The secondary winding (Windings) has 1128 and is connected to a resistor (R) with a resistance of 128 0. Calculate the maximum current flow through the resistor. Give your answer as a positive value with unit Amps to 2 decimal places. Windingp Windings VAC R Link to image/diagram (opens in new window/tab) ...

One composite contains long, aligned fibres so it is appropriate to use the ✓ estimate for composite modulus. The composite has a modulus of 85 GPa, which suggests a fibre fraction of about estimate for ✓. The other composite had the reinforcement added as fine, chopped up, particles so it is best to use the composite modulus. It is known that 72% of the second composite is reinforcement so the probable composite modulus is about A Moving to another question will save this response. <<< Question 29 of 36 > >>
