1) decrease
b) increase
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????
The first part of the question is asking about the effect of removing a resistor from a parallel circuit on the total current. To answer this question, we need to understand that in a parallel circuit, the total current is the sum of the currents through each individual branch.
When a resistor is removed from a parallel circuit, the total resistance in the circuit increases. According to Ohm's Law (which states that current is equal to voltage divided by resistance), if the resistance increases and the voltage remains the same, the current will decrease. So, the answer is option (1) - the total current will decrease.
Now, let's move on to the second part of the question. Each branch in a parallel circuit has its own resistance, and the current flowing through each branch is determined by the resistance of that branch and the total voltage applied to the circuit.
When a resistor is removed from a parallel circuit, the total resistance increases. However, the remaining branches still have the same resistance as before. Since the voltage across each branch remains the same, according to Ohm's Law, the current flowing through each of the remaining branches will also remain the same.
So, the answer to the second part is that 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 remain the same and the current flowing through each of the remaining branches will increase.
When a resistor is removed from a parallel circuit, the total resistance of the circuit increases because there is one less path for the current to flow through. According to Ohm's Law (which states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance of the conductor), if the resistance increases and the voltage remains constant, the current must decrease.
However, in a parallel circuit, each branch has its own resistance. Thus, when one resistor is removed, the overall resistance of the circuit increases, but this does not affect the resistance of the remaining branches. Therefore, the current flowing through the remaining branches remains the same.
