What is a series circuit?
A circuit in which the components are connected one after another in a single path
What happens to the voltage is a series circuit?
It is divided among the component
What happens to the current in a series circuit?
It is the same as the current from the power supply
What is a parallel circuit?
It is s circuit in which each component is connected on its own path from the power supply.
What happens to the voltage is a parallel circuit?
It is the same across each component as the supply voltage
What happens to the current in a parallel circuit
It is divided among the different paths.
What is voltage?
It is a measure of potential difference in energy between one part of a circuit and another
What is current?
It is a measure of the flow of electrons through a complete circuit.
What is resistance?
It is a measure of how much the component retricts and reduces the flow of current
How do I calculate V?
V = IR
How do I calculate I?
I = V/R
How do I calculate R
R = V/I
