The differences in resistance between conducting and insulating components can be explained by the amount of charged particles (and how much charge they hold) available to move.
Conductors have more available charge carriers than insulators. |
|
Why does resistance vary between conducting and insulating components? |
|
|
|
Resistance is a measure of how hard it is for current to flow through a material / set of components and measured in ohms, |
|
What is resistance and what is it measured in? Resistance across a copper wire |
|
|
|
Resistance is the ratio of potential difference (p.d.) to current. |
|
What is resistance the ratio of? |
|
|
|
To be able to calculate Resistance given a p.d. and current using R = V / i |
|
What equation is used to calculate resistance? |
|
|
|
To be able to calculate either a p.d. or current given the other and the resistance by rearranging R = V / i |
|
How can the equation for resistance be rearranged to find potential difference or current? |
