[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.
