Help with number 26 Holt
Chapter 20 Practice problems? The diagram is above.
26] R2 and R3 are in series and so their sum will be:
R = 7 + 7 = 14 ohms
this is parallel to a 7 ohm resistor
so, their equivalent resistance will be:
R' = [1/14 + 1/7]-1 = 4.667 ohms
this is now in series with one 7 ohm resistor and another 1.5 ohm resistor. So, the equivalent resistance of the circuit is:
Req = 4.667 + 1.5 + 7 = 13.167 ohms.
