losses in the cable ’s metallic conductors. Temperature also has effects the resistivity of the conducting surface. Resistivity is a "bulk property of material describing how well that material inhibits current flow. This is slightly different from resistance‚ which is not a physical property. If one considers current flowing through a unit cube of material (say‚ a solid metal cube that measures 1 meter on each side)‚ resistivity is defined as the voltage measured across the unit cube length (V/m) divided

level is approaching. The fuel sensor system consists of a tank-mounted float sensor and a current meter (fuel meter)‚ which are connected in series. The float-driven sensor attached to an internal rheostat offers high resistance when the tank is empty. When the tank is full‚ the resistance decreases‚ allowing more current to pass through the meter to give a higher reading. The fuel monitoring circuit works EO SANI TH H by sensing the voltage variation developed across the meter and activates

2a Homework 08 - Solutions You need a 45 Ω resistor‚ but the stockroom has only 20 Ω and 50 Ω resistors. How can the desired resistance be achieved under these circumstances?" " A. Put one 50 Ω and one 20 Ω resistor in parallel and then put that combination in series with a 20 Ω resistor." B. Put two 50 Ω resistors in series and then put that combination in parallel with a 20 Ω resistor." C. Put one 50 Ω and one 20 Ω resistor in series and then put that combination in parallel with

Experiment 13 Charging and Discharging Capacitors 1. Introduction In this experiment you will measure the rates at which capacitors in series with resistors can be charged and discharged. The time constant RC will be found. Charging a capacitor. Consider the series circuit shown in Fig. 1. Let us assume that the capacitor is initially uncharged. When the switch S is open there is of course no current. If the switch is closed at t=0‚ charges begin to flow and an ammeter will be able
