A potential difference of 19.0 V is applied across a wire of cross-sectional area 2.01 mm2 and length 949 km. The current passing through the wire is 3.096×10-4 A. a) What is the resistance of the wire?
A resistor of unknown resistance and a 50.0-O resistor are connected across a 128.0-V emf device in such a way that an 13.0-A current flows. What is the value of the unknown resistance?
When the same emf device is placed across the same two resistors in parallel, the current through the emf device is 51.0 A. What is the magnitude of the larger of the two resistances?
Plot the variation of temperature with time. To do so, you will need to solve a first-order, ordinary differential equation, with the boundary condition: T(t=0) = T1 = 318 K.

The electric potential inside a charged spherical conductor of radius R is given by V = keQ/R, and the potential outside is given by V = keQ/r. Using Er = -dV/dr, derive the electric field inside and outside this charge distribution.
A galvanometer with a full-scale sensitivity of 550 and a coil resistance of 54 is to be used to build an ammeter designed to read 7.5 at full scale. What is the required shunt resistance?
A polling company uses random digit dialing to select the households to be interviewed. In one city, in 1000 calls, 15% of the calls reach an unlisted number. This is not surprising, since 18% of the residential phones in that city are unlisted. T
