Which of the following statements about Ohm’s Law is true?

A. Increasing the voltage decreases current.
B. Keeping the same voltage and decreasing resistance decreases the current.
C. Ohm’s law relates power, current and resistance.
D. To increase the current, decrease the resistance.

To determine which statement about Ohm's Law is true, let's first understand what Ohm's Law states. Ohm's Law is a basic principle in electricity that relates voltage (V), current (I), and resistance (R). It states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to the resistance of the conductor.

Now, let's analyze each statement:

A. Increasing the voltage decreases current.

According to Ohm's Law, this statement is incorrect. Ohm's Law states that increasing the voltage applied across a conductor will increase the current flowing through it, assuming the resistance remains constant. So, statement A is false.

B. Keeping the same voltage and decreasing resistance decreases the current.

This statement is true according to Ohm's Law. Ohm's Law states that if the voltage remains constant, decreasing the resistance of a conductor will result in an increase in current. So, statement B is correct.

C. Ohm’s law relates power, current, and resistance.

This statement is incorrect. Ohm's Law doesn't directly relate power to current and resistance. However, power can be calculated using the formula P = V * I, where P represents power, V represents voltage, and I represents current. So, statement C is false.

D. To increase the current, decrease the resistance.

This statement is true. According to Ohm's Law, if the voltage remains constant, reducing the resistance of a conductor will result in an increase in current. So, statement D is correct.

To summarize, the true statement about Ohm's Law is D. To increase the current, decrease the resistance.
