2 (2 points) 3. A 200 ohm, 0.4 H relay coil is operated from a 12-V de power source by a switch with contacts that have a minimum arcing voltage of 12 V and minimum arcing current of 400 mA. It has been determined that an R-C contact protection network using a series capacitor and resistor across the switch will be used. What is the correct value of resistor (in ohms) to use? (a) 1.5 (b) 15 (c) 50 (d)-1500 What is the correct value of capacitor (in uF) to use? (a) .01 (b) or (c) 0.05 (d) 0.001 L Ja RCRL IZV LRL 2002 C2 To x10-6 400m7 304 R2-2002 C2 0.08x10-6 V=IR 12V = I (150)
