Consider the circuit shown in Figure P31.69, in which RA = 25 and RB = 7 . Tabulate the current through, and the potential difference across, each resistor.

Figure P31.69

resistor current (A) potential difference (V)

4 2 8

RA (25 ) 16/25 16

6 ?? ??

RB (7 ) ?? ??

24 ?? ??

I'm having a lot of trouble figuring this out. I know this:

V=IR

For parallel, Rtotal = R1 + R2 + ...

For series, Rtotal = (1/R1 + 1/R2+...) ^-1

Any help would be great.
