Electrical Charge
Current
Current is the rate of flow of Charge
I = Δq/Δt
Current
Voltage
Voltage (Potential Difference) is the change in energy (work done) to each coulomb of charge between two points on a circuit, or two points across an electric field

Internal Resistance of a Battery
Batteries can be thought of as having an ideal voltage supply E.M.F. (Electromotive Force) in series with an internal resistance
V = 𝛆 - Ir

Kichhoff's Laws
Kirchhoff’s Current Law
“At any junction in a circuit, the total current entering the junction equals the total current leaving the junction”
Kirchhoff’s Voltage Law
“Around any closed path of a circuit, the total of all the potential differences, V, is zero”
“At any junction in a circuit, the total current entering the junction equals the total current leaving the junction”
Kirchhoff’s Voltage Law

Ex 3F, p. 87-96 Doppler Effect
Ex 3B, p. 57-62, Two Point Source Interference (Double Slit Experiment)
Beats
two waves of a similar frequency (similar wavelength) superimpose to come in and out of phase causing constructive and deconstructive interference respectively. This causes a warbling/beat sound of frequency (fb) equal to the difference in respective frequencies
fb = | f1 - f2 |

Two Point Source Interference
- Antinodes - Path Difference = n𝜆
- Nodes - Path Difference = (n + 1/2)𝜆
Two Point Source Interference
n𝜆 = dsin(𝛳)
n: Antinodal Fringe Number
𝜆: Wavelength (m)
d: Slit-Spacing (m)
𝛳: Angle between Fringe on screen from the central position line
Iff 𝛳 is very small, then
n𝜆 = dx/L
x: Distance from Fringe on screen to central position (m)
L: Distance from slits to screen along the central position line (m)
