MORE REMARKS Notice how the concept of rms values allows the handling of an AC circuit quantitatively in much the same way as a DC circuit. QUESTION The rms current in an AC circuit: (Select all that apply.) reverses direction many times per second. is an average current, and is therefore zero. measures the magnitude of the current, as a special kind of average. is the direct current that dissipates energy at the same rate as the AC current. PRACTICE IT Use the worked example above to help you solve this problem. An AC voltage source has an output of Av = (1.41 x 10² V) sin 2xft. This source is connected to a 1.50 x 10² resistor as in the figure. Find the rms voltage and rms current in the resistor. V rms Irms max A EXERCISE HINTS: GETTING STARTED I'M STUCK! Use the values from PRACTICE IT to help you work this exercise. Find the maximum current in the circuit and the average power delivered to the circuit. - A W

An electromagnet is used to produce a uniform magnetic field between its poles, shown in figure 3 below. The field outside the gap is negligible. The coil encloses the magnetic flux. The magnetic flux density through the coil is 0.04 T and the coil has 50 turn. i.Calculate the flux through the coil ii.The current through the coil is reduced to zero at a uniform rate over a time of 2.5 s. Find the average e.m.f. induced in the coil
