It's named after an Italian scientist.
What is the unit of voltage?
Think about the scientist's name associated with this unit.
Voltage measures the difference in what?
It’s linked to energy available to move charges.
A circuit with a voltage of 24V has a total resistance of 6Ω. Using Ohm’s Law, calculate the current flowing through the circuit.
Apply Ohm's Law to find the current.
In a system where a voltage of 9V is applied to a circuit with three 3Ω resistors in series, calculate the total current flowing through the circuit.
Remember to first find the total resistance in a series circuit.
