TBR Physics Book II page 219 #39
TBR says that when both switches are closed, the initial surge of energy goes exclusively to the capacitor because they are the path of least resistance.
My question: How do you know that the capacitors are the path of least resistance? In other words, how can you compare the resistance of capacitors with resistors? Do capactiors always have less resistance (e.g., a capacitor with capacitance of 9999999999 F would have less resistance than a resistor with .000000000000000000000001 ohms)?
I guess what I'm asking is: Do we assume capacitors don't impede electron flow (have 0 resistance)?
