### Topic: Ohm's Law**Graph Explanation**The graph below represents the relationship between the current in a metallic conductor and the potential difference across the conductor at constant temperature. The resistance of the conductor is to be determined.**Graph Details**- **Title**: Current vs. Potential Difference- **X-axis (Horizontal)**: Potential Difference (V) ranging from 0 to 5 volts.- **Y-axis (Vertical)**: Current (A) ranging from 0 to 2 amperes.- **Data Representation**: The graph displays a straight line passing through the origin with a positive slope, indicating a direct proportional relationship between current and potential difference.### AnalysisOhm’s Law states that the Current (I) through a conductor between two points is directly proportional to the Voltage (V) across the two points.\[ V = I \cdot R \]where \( R \) is the resistance.From the graph, observe the slope \( (m) \):\[ m = \frac{\Delta I}{\Delta V} \]Choose two points from the graph:- Point 1: (1 V, 0.5 A)- Point 2: (4 V, 2 A)Calculate the slope:\[ \text{Slope} = \frac{2 A - 0.5 A}{4 V - 1 V} = \frac{1.5 A}{3 V} = 0.5 \, \Omega^{-1} \]The resistance \( R \) is the reciprocal of the slope:\[ R = \frac{1}{\text{Slope}} = \frac{1}{0.5 \, \Omega^{-1}} = 2 \, \Omega \]### QuestionDetermine the resistance of the conductor. Choose one:- [ ] 1.0 Ω- [x] 2.0 Ω- [ ] 0.50 Ω- [ ] 4.0 Ω

You are working in a laboratory, using very sensitive measurement equipment. Your supervisor has explained that the equipment is also very sensitive to electrical discharge from human operators. Specification tables for the equipment indicate that an electrical discharge providing even a very small amount of energy of 250 J is enough to damage the equipment. Your supervisor wants to install an apparatus that will be used to remove the electrical charge from individuals bodies before they touch the equipment. To do this, she asks you to estimate (a) the capacitance of the human body and determine (b) the charge on the body and (c) the electric potential of the body, relative to a point infinitely far away, corresponding to the energy transfer that will damage the equipment.
(a) A defibrillator sends a 6.00-A current through the chest of a patient by applying a 10,000-V potential as in the figure below. What is the resistance of the path? (b) The defibrillator paddles make contact with the patient through a conducting gel that greatly reduces the path resistance. Discuss the difficulties that would ensue if a larger voltage were used to produce the same current through the patient, but with the path having perhaps 50 times the resistance. (Hint: The current must be about the same, so a higher voltage would imply greater power. Use this equation for power: P=I2 RP = .)
You are part of a team working in a machine parts mechanics shop. An important customer has asked your company to provide springs with a very precise force constant k. You dense the electrical circuit shown in Figure P25.45 to measure the spring constant of each of the springs to be provided to the customer. The circuit consists of two identical, parallel metal plates free to move, other than being connected to identical metal springs, a switch, and a battery with terminal voltage V. With the switch open, the plates are uncharged, are separated by a distance d, and have a capacitance C. When the switch is closed, the plates become charged and attract each other. The distance between the plates changes by a factor f, after which the plates are in equilibrium between the spring forces and the attractive electric force between the plates. To keep the plates from going into oscillations, you hold each plate with insulating gloves as the switch is closed and apply a force on the plates that allows them to move together at a slow constant speed until they are at the equilibrium separation, at which point you can release the plates. You determine an expression for the spring constant in terms of C, d, V, and f. Figure P25.45 Problems 45 and 50.
