Resistance?
Opposition to current. Resists the flow of electrons around a circuit
Units for resistance?
Ohms ♎️
Which was does current flow around a circuit?
Positive to negative terminal
Equation for voltage?
V = IR
Series circuit?
All the components are in the same loop
What happens to the voltage in a series circuit?
It is split between the components
Parallel circuit meaning?
A circuit with two or more paths for electricity to flow
How does the voltage work in a parallel circuit?
Voltage is the same for each loop
Electric field?
Shows the direction a positive test charge would move
Pupils move through the corridor colliding with chairs that slow them down
Electrons move through a circuit colliding with metal ions that cause resistance
