FLASHCARD QUESTION

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) flowing 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 can be expressed as V = IR.

FLASHCARD QUESTION

Front

What is the formula to calculate resistance?

Back

Resistance (R) can be calculated using the formula R = V/I, where V is voltage and I is current.

3.

FLASHCARD QUESTION

Front

If a circuit has a voltage of 9 V and a current of 1 A, what is the resistance?

Back

Using Ohm's Law, R = V/I = 9 V / 1 A = 9 Ω.

FLASHCARD QUESTION

Front

What is the unit of resistance?

Back

The unit of resistance is the Ohm (Ω).

5.

FLASHCARD QUESTION

Front

How do you calculate power in a circuit?

Back

Power (P) can be calculated using the formula P = IV, where I is current and V is voltage.

6.

FLASHCARD QUESTION

Front

What is Watt's Law?

Back

Watt's Law states that the power (P) in an electrical circuit is equal to the product of the current (I) and the voltage (V): P = IV.

7.

FLASHCARD QUESTION

Front

If a light bulb has a resistance of 5 Ω and a current of 10 A, what is the voltage across the bulb?

Back

Using Ohm's Law, V = IR = 5 Ω * 10 A = 50 V.
