What is the electric field amplitude of an electromagnetic wave whose magnetic field amplitude is 1.80 mT?

A series RLC circuit attached to a 120 V/60 Hz power line draws 3.00 A of current with a power factor of 0.890. What is the value of the resistor?

For a science project, you would like to horizontally suspend an 8.5 by 11 inch sheet of black paper in a vertical beam of light whose dimensions exactly match the paper. If the mass of the sheet is 1.2 g, what light intensity will you need? (1 in = 2.54 cm)

a) What current is needed to generate the magnetic field strength of 10 T at a point 1.4 cm from a long, straight wire? (

LC circuits: A charged capacitor is connected to an ideal inductor. At time t = 0, the charge on the capacitor is equal to 6.00 μC. At time t = 2.00 ms the charge on the capacitor is zero for the first time. What is the amplitude of the current at that same instant?

The figure shows a 15-cm-diameter loop in three different magnetic fields. The loop’s resistance is 0.18 

Capacitors in combination: The capacitors in the network shown in the figure all have a capacitance of 5.0 µF. What is the equivalent capacitance, Cab, of this capacitor network?

Drift velocity: The diameter of a 12-gauge copper wire is 0.081 in. The maximum safe current it can carry (in order to prevent fire danger in building construction) is 20 A. At this current, what is the drift velocity of the electrons? The number of electron carriers in 1.0 cm3 of copper is 8.5 × 1022 and e = 1.60 × 10-19 C.
