Question 6 4 pts An electronic apparatus may have large capacitors at high voltage in the power supply section, presenting a shock hazard even when the apparatus is switched off. A "bleeder resistor" is therefore placed across such a capacitor, as shown schematically below, to bleed the charge from it after the apparatus is off. Circuit 1. The resistance of the bleeder resistor is much greater than the effective resistance of the rest of the circuit. How does this affect the current flowing through the resistor when the circuit is on? 2. From your answer in 1., why then is it important for the bleeder resistor to have a greater resistance? 3. When the circuit is off, how will the capacitor respond to the presence of the bleeder resistor? How does this offer protection from a shock hazard? ww Rbl
