# Question: Nine resistors each of value R are connected in a

Nine resistors, each of value R, are connected in a “ladder” fashion, as shown in Fig. 18.42.

(a) What is the effective resistance of this network between points A and B?

(b) If R = 10 Ω and a 12.0-V battery is connected from point A to point B, how much current is in each resistor?
