Explain why, if two resistors are in series, the net resistance is increased, whereas with two in parallel the net resistance is decreased.
Answers
increse because the current will reduced
the two in parallel the current is incresed so the resistance is decresed
hope u get help
Answer:
When a resistor is added to a series circuit, the current in the circuit is reduced since the current is constant throughout the circuit. This indicates that the circuit's overall resistance rises and increase.
As additional components are added to a parallel circuit, the net resistance lowers and decreases because there are more channels for the current to travel through. The potential difference between the two resistors is the same.
Explanation :
When resistors are connected in series:
When a resistor is added to a series circuit, the current in the circuit is reduced since the current is constant throughout the circuit. This indicates that the circuit's overall resistance rises and increase.
Rs=R1+R1......+RN
When resistors are connected in parallel:
As additional components are added to a parallel circuit, the net resistance lowers and decreases because there are more channels for the current to travel through. Having the same potential difference If they have various levels of resistance, the current flowing through them will be variable.
1/Rp=1/R1+1/R2...+1/Rn
The effective area of cross-section through which the current can pass rises when two resistors are linked in parallel. Since a wire's resistance is determined by
Since R=pl/a determines a wire's resistance, es
In other words, resistance is inversely proportional to cross-sectional area, so any increase in cross-sectional area reduces resistance.
