List two types of elements that would cause an electric potential drop in a circuit and one type of element that would cause an electric potential gain in a circuit.

Answer 1

In a circuit, two types of elements that would cause an electric potential drop are:

1. Resistors - These components resist the flow of electric current, causing a drop in voltage as the current passes through them.

2. Inductors - These store energy in a magnetic field when current flows through them and can cause a drop in voltage due to their opposition to changes in current.

One type of element that would cause an electric potential gain in a circuit is:

1. Voltage Sources (like batteries or power supplies) - These provide a higher potential difference, effectively increasing the voltage across the circuit when connected.
