toroidal inductor. * Measure the inductance and the resistance of an inductor. * Use an inductor to step up the voltage of a battery. * Build a circuit for lighting up white LEDs from a 1 Volt battery. This lab is a group activity. The current group assignments are given here. One lab report per group needs to be turned in on D2L. The responsibilites for the successful completion of the lab consist of three parts: The prelab, the actual lab measurements, and the writing of the report. The

Line Connector Therefore, when selecting the arrester lead on a station class arrester, there are several factors that need to be taken into consideration to ensure the arrester protection capabilities are not affected. Fault Current: When an arrester fails, the fault current through the arrester can be quite substantial. If it is important that the lead not burn through or fail mechanically, the lead should be selected to meet these criteria, Down Conductor Arrester Lead Figure 1 Transformer

DYNAMIC OCEAN SURFACE CIRCULATION Ocean Currents • are masses of ocean water that flow from one place to another. • Currents that are generated involve water masses in motion. • Surface currents develop from friction between the ocean and the wind that blows across its surface. Ocean Circulation Patterns • Higher circulating – moving current systems dominate the surfaces of the oceans. These large whirls of water within an ocean basin are called GYRES (gyros = a circle).

business, individuals and the government. A balance of payments statement can be broken down into various components. These include payments for the country's exports and imports of goods, services, financial capital, and financial transfers. The current account represents a summary of the flow of funds between one specified country and all other countries due to a purchase of goods and services, or the provision of income from financial assets. The capital account represents a summary of the flow

Since WCR Accounts payable = (Accounts receivable + Inventory) – Accounts payable, = (Accounts receivable + Inventory) – WCR = ($800,000 + $1,200,000) – $1,440,000 = $560,000 Net fixed assets Net fixed assets Net fixed assets = Total assets – Current assets = Total assets – Inventory – Accounts receivable – Cash = $5,000,000 – $1,200,000 – $800,000 – $400,000 = $2,600,000 Short-term debt Liabilities = .60 × total assets = .60 × $5,000,000 = $3,000,000 = Liabilities – Accounts payable = $3

circuit shown above, what is the value of the potential difference between points X and Y if the 6-volt battery has no internal resistance? A) 1 V A) 2 V B) 3 V C) 4 V D) 6 V Total resistance 4 Ω + ( 1/3 Ω + 1/6 Ω)-1 = 6 Ω Current = I = V/R 6 V / 6 Ω = 1 A V = 1 A 4 Ω = 4 V Therefore 2 V will be left for the parallel network More glow more flow [pic] 23. A lamp, a voltmeter V, an ammeter A, and a battery with zero internal resistance are connected as shown

Chapter 25 – Current, Resistance and Electromotive Force - Current - Resistivity - Resistance - Electromotive Force and Circuits Current Electric current: charges in motion from one region to another. Electric circuit: conducting path that forms a closed loop in which charges move. In these circuits, energy is conveyed from one place to another. Electrostatics: E = 0 within a conductor _ Current (I) = 0, but not all charges are at rest, free electrons can move (v ~ 106 m/s). Electrons

plant. V=IR P=IV P=I2R Where V represents Voltage drop, I represents Current, R represents Resistance, & P represents Power lost. This intro tells me that I will be using a plant voltage of 120V to solve the first cases. I can see that I’ll be predicting various voltage drops across a completed circuit, from a power plant to a house. Exercise 5A, Case 2 If nothing is hooked up in the house: 1.) What is the current through the supply wire? To solve this I go back to my equation, deciding
