The bleeder current should be 2 mA (approximately). Draw the circuit diagram, showing all values of voltage, current, and resistance. Measured R 1 R 2 R L Drawing Area: Jpeg Format Image Field Print Form 320 ohms 2200 ohms 1466.7 ohm Sarah Experiment 3: Voltage Dividers and Thévenin's Theorem Question 1: Refer toTable A.1. How does the load current vary with the load resistance R L ? Explain why Question 2: Refer to Table A.1. What is the effect on bleeder current I 1 as the load current increases? Explain why. Question 3: What is the effect on the voltages V A and V B at the divider taps as the load current increases ? Explain why The current and the resistance are inversely proportional, when the current increases, the load...
