Which do we do to find the equivalent of resistors in parallel?

Physics
1 answer:
Roman55 [17]3 years ago
6 0

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 :

\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}

Here,

R is the equivalent resistance

R_1\ and\ R_2 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".

Consider an insulated tank with a volume V = 2 L is separated into two equal-volume parts by a thin wall. On the left is an idea
steposvetlana [31]

Answer

given,

V = 2 L

the left is an ideal gas at  P = 100 k Pa and T = 500 K

mass is constant

 m_1 = m_2

\dfrac{P_1V_1}{RT_1} = \dfrac{P_2V_2}{RT_2}

Pressure is same because it's not changing due to process

\dfrac{V}{500} = \dfrac{2 V}{T_2}

T_2 = 1000\ K

\Delta S_{univ} = \Delta S_{sys} + (\Delta S)_{surr}

\Delta S_{univ} =m(C_v ln (\dfrac{T_2}{T_1}))+ R ln (\dfrac{V_2}{V_1})

m = \dfrac{P_1V_1}{RT_1}

m = \dfrac{100 \times 10^3 \times 2 \times 10^{-3}}{287\times 500}

m = 1.39 x 10⁻³ Kg

\Delta S_{univ} =1.39\times 10^{-3}(0.718 ln\ 2+ 0.287 ln (2)

\Delta S_{univ} =0.968\times 10^{-3}\ kJ/K

Use free fall in a sentance
Softa [21]
Free fall means rapid fall or a downward motion due to gravity. Sentence example: When Joe was accidentally bumped by Sarah, he was sent towards a free fall down the escalator, leading to a serious injury on his arm and two legs.
