1. 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

2. 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
