a. A mechanical switch, having silver contacts, is used to control a 24-V dc relay with a winding resistance of 240 Ω and inductance of 10 mH. If the switch contacts are protected by an R-C network, what value resistor and capacitor should be used?
b. If a 100-Ω resistor is used in the contact protection network, then what value capacitor would be required for the protection network to be non-oscillating (over damped)?
