Question: According to Ohm\'s Law, if the resistance in a circuit is doubled while keeping the voltage constant, what happens to the current?

Options:

Correct Answer: It halves

Solution:

According to Ohm\'s Law, if resistance is doubled while voltage remains constant, the current will be halved.

According to Ohm's Law, if the resistance in a circuit is doubled while keeping the voltage constant, what happens to the current?

According to Ohm's Law, if the resistance in a circuit is doubled while keeping the voltage constant, what happens to the current?

Step 1: Understand Ohm's Law, which states that Voltage (V) = Current (I) x Resistance (R).
Step 2: Identify that in this scenario, the voltage (V) is constant.
Step 3: Recognize that if the resistance (R) is doubled, we can express it as R' = 2R.
Step 4: Substitute the new resistance into Ohm's Law: V = I' x (2R), where I' is the new current.
Step 5: Since V is constant, we can set the original equation equal to the new one: I x R = I' x (2R).
Step 6: Simplify the equation: I = I' x 2.
Step 7: Rearrange the equation to find the new current: I' = I / 2.
Step 8: Conclude that if resistance is doubled, the current is halved.

Ohm's Law – Ohm's Law states that the current (I) in a circuit is directly proportional to the voltage (V) and inversely proportional to the resistance (R), expressed as I = V/R.
