Circuits

Front

What is the total resistance in a series circuit?

Back

The total resistance is equal to the sum of the individual resistances.

Front

What happens to the current in a parallel circuit when one branch is disconnected?

Back

The current continues to flow in the other branches; only the disconnected branch is affected.

Front

What is the effect of unlike charges on each other?

Back

Unlike charges attract each other.

Front

What is the effect of like charges on each other?

Back

Like charges repel each other.

Front

What instrument is used to test if materials conduct electricity?

Back

A multimeter or conductivity tester.

Front

In a parallel circuit, how does the total resistance compare to the individual resistances?

Back

The total resistance is less than the smallest individual resistance.

Front

What is Ohm's Law?

Back

Ohm's Law states that V = IR, where V is voltage, I is current, and R is resistance.

Front

What is the unit of electrical resistance?

Back

Ohm (Ω).

Front

What is a series circuit?

Back

A circuit in which components are connected end-to-end, so the current flows through each component sequentially.

Front

What is a parallel circuit?

Back

A circuit in which components are connected across common points or junctions, allowing multiple paths for current.
