This pinch effect has been used in designing fusion reactors. It can be demonstrated by making an empty aluminum can carry a large current parallel to its axis. Let R represent the radius of the can and I the current, uniformly distributed over the can's curved wall. (a) Determine the magnetic field just inside the wall.
REMARKS This calculation demonstrates that under normal circumstances, the gravitational force on a current carrying conductor is much greater than the magnetic force due to Earth's magnetic field. QUESTION What magnetic force is exerted on a wire carrying current parallel to the direction of the magnetic field?
If the current in one wire is 1.75 A and the current in the other wire is 3.05 A running in the opposite direction, determine the magnitude and direction of the force per unit length the wires exert on each other. 117"105x magnitude What physcal quantities determine the force per unit length produced by two long, straight parallel, current ...
Question: Part III. MEASURING VOLTAGE AND CURRENT in Parallel CircuitsP6. Build a circuit of two bulbs in parallel followed by one bulb in series. (see photo) series light "bulb 3 ". Draw ammeters where you would measure the currents through each bulb, out of the power source, and into the power source.P7.
For each combination, find the voltage and the current for every element, thus, you'll identify contradictions.A 2-A current source in parallel with a short circuit.A 2-A current Which of the following combinations of circuit elements are self - contradictory?
Consider two two long, straight, parallel, current-carrying wires, separated by a distance d = 2.6 cm, as shown in the figure. The left wire is directed out of the page with current I 1, and the right wire is directed into the page with current I 2. The point P is a distance d from both wires, so the wires and the point form an equilateral ...
Question: Your boat departs from the bank of a river that has a swift current parallel to its banks. Part A If you want to cross this river in the shortest amount of time, you should direct your boat A. perpendicular to the current. B. upstream. C. downstream. D. so that it drifts with the current.
Question 2.2: Yes, when the switch was open, all the current from the circuit was drawn by bulb D. When the switch is closed, bulb E becomes parallel to bulb D, and now the current is split into two arms according to resistance. This is according to …View the full answer
Use your rule for current in parallel to explain why this would happen. Hint: Try treating the corners of your series circuit as junctions. How many currents go in? How many currents go out? Β Ι Ο Score: 0/2 2. For parallel circuits, you saw that the potential difference across each resistor was the same as the potential difference of the ...
Consider a co-current (parallel flow) heat exchanger with the following properties: - The cold liquid enters at a temperature of 20 C and rises 20 C in temperature by the time it exits the heat exchanger. - The hot liquid leaves the heat exchanger at 61 C.
