Answer:

Potential difference.

Resistance.

Resistance, Area of cross section.

True.

Answer 2

1. The unit of potential difference generated between two points is called the Volt and is generally defined as being the potential difference dropped across a fixed resistance of one ohm with a current of one ampere flowing through it. In other words, 1 Volt equals 1 Ampere times 1 Ohm, or commonly V = I*R.
2. The hindrance to the flow of electric charge is known as Resistance. ... In an electric circuit, the potential difference across the two terminals encourages the flow of current while at the same time the resistance discourages the flow of current.

• The resistance of a given piece of wire depends of three factors: the length of the wire, the cross-sectional area of the wire, and the resistivity of the material composing the wire.

• An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.
