- Compute for the voltage Vbc in the circuit shown below.Total resistance in a parallel circuit is less than your smallest resistor. The reason for this prob is that the total resistance has to divide, (or) split up. Can you help me to conceptualize this, which would get into the difference between parallel versus series circuit.If two resistors with resistances R, and R, are connected in parallel, as in the figure below, then the total resistance R, measured in ohms (N), is given by 3D R2 If R, and R2 are increasing at rates of 0.3 N/s and 0.2 N/s, respectively, how fast is R changing when R, = 60 N and R2 = 90 N? (Round your answer to three decimal places.) N/s R
