Question

Chapter 21, Problem 1CQ

To determine

The reason for which the presence of a phase difference between the current in an ac circuit and the potential difference across a capacitor in the same circuit.

Expert Solution & Answer

Answer to Problem 1CQ

The current in the ac circuit and the potential difference across the capacitor in the same circuit varies as one among these quantities vary and they never comes in phase since their variation is in such a way that increase of one causes the decrease of the other. Hence, always there exist a phase difference between these parameters.

Explanation of Solution

As the alternating current flows through a circuit containing an uncharged capacitor, charge begins to accumulate on the capacitor plate. The potential across the capacitor increases as the charge accumulation increases. This voltage development will be in opposite in direction of the emf of the generator. The increase in voltage across the capacitor leads to the decrease in current in the circuit.

The change of direction of emf from the generator, causes the decrease in voltage across the capacitor and thereby increase in current through the circuit. Since this process is continued as long as the ac supply maintained, the current in the circuit and the potential difference across a capacitor in the same circuit never comes in phase.

A high-speed lifting mechanism supports an 881 kg object with a steel cable that is 22.0 m long and 4.00 cm^2 in cross-sectional area. Young's modulus for steel is 20.0 ⋅10^10 Pa. Determine the elongation of the cable.

Namor, from Wakanda Forever, sits on a throne at the bottom of the ocean in a city called Talocan (and Atlantis in the comics). Assuming he, including his gold headdress, has a density of 1085 kg/m3 and that Namor is surrounded by salt water with a density of 1027 kg/m3, what is Namor’s normal force while sitting underwater? Take Namor’s mass as 285. kg and solve as if he has a uniform density.

To get there they need to travel through an area of salt-water, which seems to also be a magical portal, before arriving in a dry area. Judging by the time Maui and Moana spend falling through the water, it seems they dive 3440. ft deep. Assume the portal is non-magical salt-water, with a density of 1027 kg/m^3. Given that the air pressure above the portal is 1.013 ⋅10^5 Pa, what is the pressure when they are 3440. ft deep? 1 m = 3.28 ft. Moana would have a surface area of 1.30 m2. How much force would be acting on her at the bottom of this portal?
