Question: If the total resistance in a Wheatstone bridge is increased, what happens to the current in the circuit?

Options:

Correct Answer: It decreases

Solution:

According to Ohm\'s law, if the total resistance increases, the current in the circuit decreases.

If the total resistance in a Wheatstone bridge is increased, what happens to the current in the circuit?

If the total resistance in a Wheatstone bridge is increased, what happens to the current in the circuit?

Step 1: Understand that a Wheatstone bridge is a circuit used to measure resistance.
Step 2: Recall Ohm's law, which states that current (I) is equal to voltage (V) divided by resistance (R).
Step 3: Note that if the total resistance (R) in the circuit increases, the current (I) will change.
Step 4: Since current is inversely proportional to resistance, an increase in resistance means the current will decrease.
Step 5: Conclude that if the total resistance in a Wheatstone bridge is increased, the current in the circuit decreases.

Ohm's Law – Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance.
Wheatstone Bridge – A Wheatstone bridge is a circuit used to measure unknown resistances by balancing two legs of a bridge circuit.
