[SOLVED] current and potential difference, simplifying circuit diagrams
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.
