Current Flashcards
What is current
The flow of electric charge
What are the conditions for current to flow?
A complete closed circuit if there’s potential difference.
What is the value of current throughout the circuit?
In a series circuit, the value of current is the same anywhere in the circuit
What is potential difference?
Potential difference is the driving force that pushes the charge around.
What is resistance?
Resistance is anything in the circuit which slows the flow down.
What does the current depend on?
The potential difference and the resistance across the component.
How does the resistance affect the current?
The greater the resistance across a component, the smaller the current that flows through it (for a given potential difference)
