It's related to how fast electrons move.
What is the unit of electric charge?
Think about the definition of charge.
True or False: Resistance decreases the flow of electric current.
Consider what resistance does in a circuit.
A circuit with a 12V battery and a resistance of 4Ω. Calculate the current flowing in the circuit.
Make sure to use the correct formula mentioned in class.
If a circuit consumes 60W of power at a voltage of 120V, what is the current flowing through the circuit?
Remember the power formula we discussed.
