Phys Chapter 6 & 7

Ohm's Law states

• that for constant voltage, a greater resistance means more current will flow.

• a relationship between voltage, current, and charge.

• that less current flows when a higher voltage is applied.

• that the current in a circuit increases if the potential difference increases.

If you multiple amp X ohm, the answers will be in units of

• current.

• power.

• potential.

• resistance.

What is it that travels through an electric circuit at near the speed of light?

• a potential difference.

• electrons.

• protons.

Electrical resistance is a property of conductors that is measured in units of

A neutrally charged atom that gains one or more electrons is called a(n)

• negative ion.

• position.

• positive ion.

• deionized atom.

An electric current is measured in units of

• coulomb.

• amp.
