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 usually expressed as V = I × R.

FLASHCARD QUESTION

Front

What is the formula to calculate current in a circuit?

Back

The formula to calculate current (I) in a circuit is I = V / R, where V is the voltage and R is the resistance.

FLASHCARD QUESTION

Front

What is the unit of measurement for resistance?

Back

The unit of measurement for resistance is Ohms (Ω).

FLASHCARD QUESTION

Front

If a circuit has a voltage of 12 volts and a resistance of 4 ohms, what is the current?

Back

Using Ohm's Law, I = V / R = 12V / 4Ω = 3 Amps.

FLASHCARD QUESTION

Front

How does increasing resistance affect current in a circuit?

Back

Increasing resistance in a circuit decreases the current, assuming the voltage remains constant.
