c) remain the same and the current flowing through each of the remaining branches ____________________.
removing one resistor makes total resistance greater. What does this imply on Ohms Law?
okay so the total current will decrease, but what about the second part?
and the current flowing through each of the remaining branches ____.
remains the same????
When one resistor is removed from a parallel circuit, the total current will increase. To understand why, let's break it down step by step:
1) When a resistor is removed from a parallel circuit, the total resistance of the circuit decreases. This is because with one less resistor, there is less obstruction to the flow of current in the circuit.
2) According to Ohm's Law, the current in a circuit is directly proportional to the voltage across the circuit and inversely proportional to the resistance. This means that with a decrease in resistance, the current in the circuit will increase, given that the voltage remains constant.
So, in summary:
- The total current in the circuit will increase when a resistor is removed because the total resistance of the circuit decreases.
- The current flowing through each of the remaining branches will stay the same because the voltage across each branch remains unchanged, and the decrease in total resistance is now distributed among the remaining resistors.
Therefore, the correct answer is:
b) increase
c) remain the same and the current flowing through each of the remaining branches remains the same.
If one resistor is removed from a parallel circuit, the total current will actually increase.
When a resistor is removed from a parallel circuit, the total resistance of the circuit decreases. According to Ohm's Law (V = I * R), if the resistance decreases, and the voltage across the circuit remains constant, the current through the circuit will increase.
In a parallel circuit, the removal of a resistor does not affect the other branches of the circuit. The current flowing through each of the remaining branches will remain the same. This is because each branch of a parallel circuit has its own separate current path, and removing a resistor from one branch does not affect the current flow through the other branches.
