Unformatted text preview: d) If 100V is used to obtain the same dissipation rate, what should be the new length? Q3: Three cylindrical resistors X, Y and Z are connected in a circuit as shown in the figure. X and Y have the same length L and cross-sectional area A. The resistor Z has length 2L and cross-sectional area A/2. The resistivity constants of the materials are shown in the figure. Resistors are connected to an ideal battery of 84 V. If the resistance of Y is 6 ; a) Calculate the equivalent resistance of the circuit. b) Find the rate at which electrical energy is dissipated in the resistor X. X Y = 6Ω Z 84 V 2 ρ ρ ρ...
