Runs at a higher temperature Answer 1Choose...DCAC More dangerous to transfer Answer 2Choose...DCAC Easy to produce Answer 3Choose...DCAC Easier to transform voltages Answer 4Choose...DCAC Voltage remains at a constant value Answer 5Choose...DCAC Cheaper to produce

A highly inductive load, such that load current can be assumed constant, is to be supplied from a 230 V, 50 Hz, single-phase supply by a fully-controlled and a halfcontrolled bridge. Compare the average load. Voltage provided by each bridge at firing angles of 30° and 90°. Neglect device voltage drops.

2. Given:VCC: 16 voltsRB1: 7000 ohmsRB2: 50 ohmsRB3: 50 ohmsRB4: 1500 ohmsB=beta: 100RE: 750 ohmsRC: 500 ohmsVCE: ? volts

Since R1=18.10Kohm, R2=67.58Kohm, RC= 1.08Kohm, RE= 3.23Kohm, VCC=14.00V, Beta=241.00 in the circuit given in the figure, calculate the IC current by doing a complete analysis. When performing your operations, 2 steps will be taken after the point. choose the closest one from the stylish ones according to the +/-10% margin of error. There is only 1 correct answer to the question.
