Problem 21CQ

(a) What is the potential difference going from point a to point b in Figure 21.47? (b) What is the potential difference going from c to b? (c) From e to g? (d) From e to d?

Step-by-Step Solution:
Step 1 of 3

Solution 1CQ

1.  potential difference from point a to b is -( 20Ω) I3
2. Potential difference going from c to b Vbc is  Vbc  = I2 ( 8Ω )
3. Potential difference going from e to g  Vgc = -3V + I3 ( 0.25Ω)
4. Potential difference going from e to d Vdc  is    Vdc  = 24V + I2  ( 0.75Ω )
