12-22. In the figure, what are
(a) the current through the 47 W resistor?
(b) the direction of the current through the 47 W
resistor?
(c) the potential difference VA - VB? VB
- VA?
(d) the voltage across the 84 W
resistor?
(e) the potential at point C, if we define the potential at the
negative
terminal of the battery to be zero?
ACCUMULATED SOLUTION
Correct
The total current in the circuit is given by:
(A) I
= R/V
(B)
I = RV
(C) I
= V/R
