Opposite charges (attract/repel). 1,2

The ends of a magnet are called poles The ends of a magnet are called _____________ . 1,3

a certain resistor is 6.2 A, and R = V/I so 110 / 6.2 = 18 Ω If the current in a certain resistor is 6.2 A, and the voltage across the resistor is 110 V, what is the resistance? 1,4

insulator glass 2,1

series 2,2

Draw the magnetic field lines for Field lines will repel (never touch) Draw the magnetic field lines for 2,3

When a VCR is connected across 9.5 A current in it. What is the P = IV so (9.5)(120) = 1,140 W When a VCR is connected across a 120 V outlet, the VCR has a 9.5 A current in it. What is the power rating of the VCR? 2,4

insulator plastic 3,1

Current = amperes or amps; resistance = ohms or Ω What are the units for: CURRENT and RESISTANCE 3,2

What is a magnetic domain? A region composed of atoms whose magnetic charges are in the same direction. What is a magnetic domain? 3,3

attraction 3,4

conductor Current flows easily 4,1

Friction caused by rubbing Static electricity Friction caused by rubbing two objects together induces what? 4,2

The poles of the Earth have what charges associated with North = the negative end, South = the positive end The poles of the Earth have what charges associated with them? 4,3

What type of energy allows us to have light, television, and Electromagnetic energy What type of energy allows us to have light, television, and engines? 4,4

High resistance to current insulator High resistance to current 5,1

Control the amount of current traveling through the circuit. What do resistors do? 5,2

Explain how magnets are used on sky trains like the MagLev. The repelling of like magnetic poles due to the reflection of the magnetic pole on the track as the train moves, allow the train to ride above the track. Explain how magnets are used on sky trains like the MagLev. 5,3

Explain how flashlights work. Two batteries inside, current flows out the – end and into the metal on the inside of the plastic casing, switch closes the circuit so current travels to bulb lighting it. Explain how flashlights work. 5,4
