Question

$\huge\red{\underline{\boxed{\odot\mid{\bf{Question:-}}}}}$
What is Current?
What is potential difference? ​

Answer 1

Answer:

Current is measured through a component. Potential difference is the energy used between two points in a circuit, therefore it is measured between two points either side of a component. We describe this as the potential difference measured across a component.

Answer 2

Answer:

$\huge \underline \bold \red{answer}$

▶An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.

▶ Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit.
