Electricity
Electrostatic charge
Created by friction
Measured by electroscope
Positive charge
Same charge - repel
Different charge - attract
Negative charge
Van De Graff Generator
Ohm's Law
The relationship between the quantities of the 3 electrics is
Between current ( I )
i = E/R
Voltage (E)
E = I x R
Resistor (R)
R = E/I
Series and Parallel circuits
Difference Between Series and Parallel Circuits
Series
The same amount of current flows through all the components
In an electrical circuit, components are arranged in a line
When resistors are put in a series circuit
If one component breaks down, the whole circuit will burn out.
If Vt is the total voltage then it is equal to V1 + V2 +V3
Parallel
The current flowing through each component combines to form the current flow through the source.
In an electrical circuit
When resistors are put in a parallel circuit, the voltage across each of the resistors is the same
If one component breaks down, the whole circuit will burn out.
If Vt is the total voltage then it is equal to V1 + V2 +V3
Resistance Calculations
the required resistance is calculated from the formula "R=V/I"
which gives us 12/0.015=800 Ohms (see below for 'Vf').
