Which wire has the largest resistance? Which has the smallest? Different Resistances – These 4 wires have different lengths, Areas and Resistances Which wire has the largest resistance? Which has the smallest? Why? How would this affect current? B C A D Elec L4 – WS1
Different Resistances – The rheostat, or variable resistor This is a variable resistor. Electricity goes through The top easily, but to go through The thin long wire coil at the bottom is difficult The pictures below show the rheostat set to high, medium and low resistance. But which on is which? B C A Elec L4 – WS1
