In your new job at an engineering company, your supervisor asks you to fabricate a resistor that has a resistance of R = 0.100 Ω and no change in resistance with temperature. She suggests making the resistor from lengths of cylindrical carbon and Nichrome wires of equal radius, placed end-toend. She wants the combination to fit into a machine that allows for a radius of the resistor to be r = 1.50 mm. What are the lengths of the two segments of the resistor?

Explain why R=R0(1 + a?T) for the temperature variation of the resistance R of an object is not as accurate as P=P0(1 + a?T) which gives the temperature variation of resistivity P.
In your new job at an engineering company, your supervisor asks you to fabricate a resistor that has a resistance of R = 0.130 Ω and no change in resistance with temperature. She suggests making the resistor from lengths of cylindrical carbon and Nichrome wires of equal radius, placed end-to-end. She wants the combination to fit into a machine that allows for a radius of the resistor to be r = 1.32 mm. What are the lengths of the Nichrome segment and the carbon segment of the resistor (in m)?
In these two examples, what exactly happens if the current goes from left to right? For the first example, when t = 0, where does the charge go? I know that after a long time, the capacitor will fill up and all the current goes through the resistor, but is it the same for t = 0? For the second example, I know that at t=0, all the current goes through the wire, but after a while all the current will go through the resistor?
In (Figure 1), the battery has negligible internal resistance and EMF = 44.0 V. R1 = R2 = 3.40 Ω and R4 = 3.70 Ω. What must the resistance R3 be for the resistor network to dissipate electrical energy at a rate of 275 WW?

The total current going through the circuit is I = 4.5 A. Express the equivalent resistance R of the combination of R1, R2, R3, R4, R5, and R6, and use it to calculate the numerical resistance R in Ω. Express the potential difference between a and b, ΔV, in terms of the total current I and the equivalent resistance of the entire circuit R. Then use this to calculate the numerical value of ΔV in V.
