C2 a) A 100 kW belt driven shunt generator running at 300 rpm on 220V bus-bar, continues to run as a motor when the belt breaks, taking 10 kW. What will be its speed? Take the voltage drop per brush as IV/brush. Given R, = 0.025 ohm & Rsh=60 ohm. [4 Marks] b) A de shunt generator has an induced voltage on open circuit of 126 volts. When the machine is on load the voltage is 120 V. Find the load current if the field circuit resistance is 14 22 and armature resistance is 0.02 2. 13 Marks]
