Question

For the circuit shown, R1= R3 = R9 = R11 = 118.0 Ohms, the rest of the resistors are 236.0 Ohms. a) Without doing any simplification (or combination) identify the number of pairs E of resistors (that is 2 resistors) that are in b) Without doing any simplification (or combination) identify the number of pairs of resistors (that is 2 resistors) that are in parallel. c) Find R12 the equivalent resistance of resistors R1, and R2. d) Find R123 the equivalent resistance of resistors R1, R2, and R3. e) Find R12345 the equivalent resistance of resistors R1, R2, R3, R4, and R5.

Explanation / Answer

a) 1 pair of resistor(ans)

b) 1 pair(ans)

c) R12 = 118+236 = 354 ohm (ans)

d)R123 = 118*354/ (118+354) = 88.5 ohm(ans)

Now, R1234 = 88.5+236 = 324.5

e) R12345 = 236*324.5/(236+324.5) =136.75 ohm(ans)
