A RC circuit is constructed with a (initially uncharged) 5.00-µF capacitor and a 5.00-
ohm resistor, which are connected in series to an ideal battery with emf 60.0 V. At a
certain time after the circuit is connected, it is found that heat is being produced in
the resistor at a rate of 300 W. How much energy is stored in the capacitor at that
time (in Joules)?

Digital medical thermometers determine temperature by measuring the resistance of a semiconductor device called a thermistor (which has thermal coefficient alpha = -0.08 (oC-1) when it is at the same temperature as the patient. What is a patient’s temperature if the thermistor’s resistance at that temperature is 84% of its value at the regular human body temperature, which is 36.5 oC.

When a straight wire is warmed, its resistance is given by R = R0,[1 + a(T T0)] according to Equation 27.20, where a is the temperature coefficient of resistivity. This expression needs to be modified if we include the change in dimensions of the wire due to thermal expansion. For a copper wire of radius 0.100 0 mm and length 2.000 m, find its resistance at 100.0C, including the effects of both thermal expansion and temperature variation of resistivity. Assume the coefficients are known to four significant figures.arrow_forwardThe student engineer of a campus radio station wishes to verify the effectiveness of the lightning rod on the antenna mast (Fig. P21.71). The unknown resistance Rx is between points C and E. Point E is a true ground, but it is inaccessible for direct measurement because this stratum is several meters below the Earths surface. Two identical rods are driven into the ground at A and B, introducing an unknown resistance Ry. The procedure is as follows. Measure resistance R1 between points A and B, then connect A and B with a heavy conducting wire and measure resistance R2 between points A and C.
