FLASHCARD QUESTION

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. It is expressed as V = I × R.

FLASHCARD QUESTION

Front

What is the relationship between voltage, current, and resistance?

Back

According to Ohm's Law, the relationship is defined by the formula V = I × R, where V is voltage, I is current, and R is resistance.

FLASHCARD QUESTION

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, so the same current flows through all components. In a parallel circuit, components are connected across the same voltage source, allowing multiple paths for current to flow.

FLASHCARD QUESTION

Front

What is the unit of current?

Back

The unit of current is the Ampere (A), commonly referred to as Amp.

FLASHCARD QUESTION

Front

What happens to the total resistance in a series circuit?

Back

In a series circuit, the total resistance is the sum of the individual resistances: R_total = R1 + R2 + R3 + ...
