Electricity

Front

Resistance is measured in a unit called _____?

Back

ohm

Front

The tendency for a material to oppose the flow of electrons is called _____?

Back

resistance

Front

Items with opposite charges _____ each other?

Back

attract

Front

Electricity that changes direction as it flows is called _____?

Back

Alternating current (AC)

Front

What happens to the total resistance in a parallel circuit when more resistors are added?

Back

It decreases

Front

What is the formula for calculating resistance in a circuit?

Back

R = V/I, where R is resistance, V is voltage, and I is current.

Front

What is the difference between direct current (DC) and alternating current (AC)?

Back

DC flows in one direction, while AC changes direction periodically.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Front

What is the effect of temperature on resistance?

Back

Generally, as temperature increases, the resistance of a conductor also increases.

Front

What is a short circuit?

Back

A short circuit occurs when there is a low-resistance connection between two conductors, allowing excessive current to flow.
