Which do we do to find the equivalent of resistors in parallel?
1 answer:
Answer:
We sum the inverse of each resistance and then invert the sum.
Explanation:
The equivalent resistance in case of parallel combination of resistors is given by the formula as :
Here,
R is the equivalent resistance
are individual resistors that are connected in parallel
We can find the value of R as :
- Firstly, we add the inverse of the individual resistances.
- Secondly, we invert the sum that we get in above step.
So, the correct option is (a) "We sum the inverse of each resistance and then invert the sum".

Answer:
The pressure value changes 400 % relative to the initial value.
Explanation:
Let suppose that the gas behaves ideally and represents a closed system, that is, a system with no mass interactions so that number of moles is conserved (). Since the variables involved in the isothermal process are pressure (
) and volume (
). Finally, the process is represented by the following relationship:
(1)
Where:
- Initial and final pressures.
- Initial and final volumes.
If we know that ,
and
, then the final pressure of the closed system is:
The pressure value changes 400 % relative to the initial value.
<h2>Hello!</h2>
The answer is: Coulomb's law equation.
<h2>Why?</h2>The Coulomb's law states that the strength of an electric field (between two charges) can be calculated by multiplying their charges and dividing it into the square of the distance between their centers.
Where:
E = Electric Field Strenght
d = separation between charges (m)
