The full cycle of alternating current consists of two half cycles. For one half, current is positive and for second half, current is negative.
Therefore, for an AC cycle, the net value of current average out to zero. While the DC ammeter, read the average value. Hence, the alternating current cannot be measured by DC ammeter.

2. In the 2010 film Inception, there is a scene in which Eames uses a defibrillator to resuscitate Fischer's heart and deliver the needed kick to pull Cobb and Ariadne out of a dream again, trying to avoid a spoiler a little bit. A defibrillator is actually a very simple device that consists of an RC circuit powered by a DC source. When the circuit is in one position, the capacitor in the defibrillator charges, doing so with a time constant T. When the defibrillator is used, the capacitor discharges with a time constant T, through the patient's body, which acts as a resistor (as shown). The optimal capacitance in a defibrillator circuit is C = 60 F and the human heart has an impedance of Z = 40. The pulse delivered by the defibrillator will discharge 95% of the charge stored. The charging of the defibrillator usually works by means of multiple charging cycles using lithium-ion batteries run through a step-up transformer, but this works like applying a voltage directly with an E = 2000 V DC source. a. How long does it take to deliver the defibrillator pulse to the patient? b. In the film, the bunker where Fischer is being defibrillated is in level 3 of the dream, so 10 hours of reality time equates to 10 days of level 3 time. If the defibrillator is charged using the single 2000 V source across a 70 k resistor (and again charges up to 95%), how much "real-world" time does this take?
