Suppose you have a DC power supply connected in series with two identical resistors by low-resistance connecting wires. You set the power supply to a potential difference of 6.0 V. Which of the following statements, if any, hold true? The same potential difference will appear across each resistor. The same amount of current will flow through each resistor. The same amount of current will flow through the power supply as flows through each resistor. The potential difference across each resistor...

Electrical resistors have a design resistance. The resistors are produced by a machine with an output that is Normally distributed with mean 501 ohms and standard deviation 3 ohms. Resistance below 498 ohms and above 508 ohms are rejected. Find: ( The proportion that will be rejected: (4marks) (1) How much the standard deviation would need to be reduced (leaving the mean at 501 ohms) so that the proportion of rejected below 498 ohms would be halved. (8marks)

Using Matlab When several resistors are connected in an electrical circuit in parallel, the current through each of them is given by in=vs/Rnwhere in and Rn are the current through resistor n and its resistance, respectively, and vs is the source voltage. The equivalent resistance, Req, can be determined from the equation 1/Req=1/R1+1/R2+1/R3+.......+1/Rn. The source current is given by is , and the power, Pn, dissipated in each resistor is given by . is=vs/Req, and Pn=vsin. Write a program in...
