be A. Now, consider the resistances between C and D. If I is the current in the Ω resistor, and I in the Ω resistor, I × = I × , i.e., I = I But, I + I = I = A Thus, I =       A, I =       A that is, the current in the Ω resistor is ( / ) A, while the current in the Ω resistor is ( / ) A. (c) The voltage drop across AB is V AB = I × = A × Ω = V, This can also be obtained by multiplying the total current between A and B by the equivalent resistance between A and B, that is,
