Topic 1: Calculating % UncertaintyThe percentage uncertainty in a measurement can be calculated using:
Percentage uncertainty =Uncertainty of measurement
Measurement× 100%
Rules for combining percentage uncertainties
Rule 1: Multiplying a measurement by a constant does not change the percentage uncertaintyRule 2: If you multiply, or divide, two or more measurements, you need to add their percentage uncertainties to find the total percentage uncertaintyRule 3: If a measurement is raised to a power, its percentage uncertainty is multiplied by that powerRule 4: If you add or subtract two measurements, the absolute uncertainty is the sum of each contributing absoluteuncertainty.
Percentage uncertainty =Half the range
Mean× 100%
Percentage difference =Difference between result and known value
Known value× 100%
Resultswith % uncertainties< 5% are deemed
repeatable

Topic 1: Combining UncertaintiesSummary of the rules for finding the uncertainty of a quantity found by combining other values in a formula e.g.Can of length L = 115 mm ± 2 mm, diameter d = 66.0 ± 0.6 mm. Find the volume of the can and the uncertainty:
1. Convert the uncertainties you have been given to percentage uncertainties (%U)
%𝑈 𝑖𝑛 𝐿 =2
115× 100% = 1.7% % 𝑈 𝑖𝑛 𝑑 =
0.6
66.0× 100% = 0.9%
2. Find the value you have been asked to calculate, one step at a time. At each step calculate the percentage uncertainty of each quantity you find using the rules on the previous slider = 𝑑 ÷ 2 𝑟 = 66 ÷ 2 = 33𝑚𝑚 = 0.33𝑚Using Rule 1: %U on r =0.9%
𝐴 = 𝜋𝑟2 𝐴 = 𝜋 × 0.332 = 0.0034𝑚2
Using Rules 1 and 2: %U on A = %U on r + %U on r = 0.9% + 0.9% = 1.8%
𝑉 = 𝐿 × 𝐴 𝑉 = 0.115 × 0.0034 = 3.91 × 10−4𝑚3
Using Rule 2: %U on V = %U on L + %U on A = 1.7% + 1.8% = 3.5%
3. Convert the final percentage uncertainty back to an absolute uncertainty3.5% of 3.91 × 10−4𝑚3 = 1.4 × 10−5𝑚V = 39.1 ± 1.4 × 10−5𝑚

Topic 3: Resistors in series and parallel
Kirchoff’s rules:
3434video videovideo www www photo page:www photo photo34 35 36
Junction Rule (Charge conservation)
At each junction, charge is conserved, so the charge entering the junction equals the charge leaving.
Loop Rule (Energy conservation)
The net charge, or potential difference, for any closed path around a circuit will be zero.
Filament lamp
As V goes up, I goes up but it is not directly proportional. The line curves because the resistance is increasing with increasing heat.

Determine the electrical resistivity of a material
Topic 3: Potential divider
The potential difference is the drop in voltage from one side of a component to the other. Think of it as a waterfall; water finally has to drop to river level but it can do so in a number of steps:
R2
R1 V1
V2
Vtot
If you know the current in the circuit and Vtot, then you can find V1, V2 etc. using V = I R
For the same value of Vtot, if the value of R1 is increased, the proportion of the potential ‘dropped’ across V1 will also increase – the V1
reading will go up.
Replacing fixed resistors such as R1 with thermistors or Light Dependent Resistors will change the values for R1
and hence R2, V1 and V2. with changing temperature or light intensity.
A
A rheostat and potentiometer can be used as potential dividers.

Assuming that the wire is of uniform resistance, as the voltmeter moves further from A towards B, the potential drop that is measured increases.
Topic 3: Current carrying wires
I = n q v A

Topic 3: Core practical 3
EMF (Electro Motive Force) of a power supply is the energy given to each coulomb of charge passing through it. In other words: Joules / Coulomb (Definition of the Volt)
Some of the energy given to these charges is lost in the Internal resistance of the power supply itself. The terminal potential, what’s left, is only equal to the EMF when the current is zero.
A car battery will have a very low internal resistance whilst an EHT supply will have a very high oneTerminal
potential
EMF
rR
The terminal potential is less than the EMF, unless no current flows, and the current supplied is the EMF / total resistance (R+r)

Determine the e.m.f. and internal resistance of an electrical cell.
Electrons (negative charges) collide with the (positive) ions in the metal lattice. Electrical Energy (Kinetic Energy) is transferred to Thermal (Heat) Energy.
Increasing the P.D. or increasing the temperature causes more energy transfer, to the ions in the lattice. More collisions occur reducing drift velocity BUT, for a semiconductor, more charge carriers (n) are released.

Topic 3: Resistance and temperature
Increasing the number of charge carriers reduces the resistance and, as temperature increases, the increased lattice vibrations cause an ntc (negative temperature coefficient) thermistor to do just this. The opposite of a filament lamp (see shape to right).
