Hi all,
I'm doing a lab now to determine the relationship between the resistance of a resistor (colour-coded ones) and the energy and power dissipated. What kind of relationship is expected between the variables R and P, or R and E?
The way I carried out the lab was to use different resistors (resistances known), and observe the change in the current using an ammeter in series. I observed that as resistance increases, current decreases. This is expected. Is power meant to be constantly varying, or is it meant to be constant?
Thanks for any help.
