Para calcular la descarga de un condensador a través de resistencias, podemos usar la ley de descarga de un condensador, que se expresa como:

V_c = V_f \cdot e^{-\frac{t}{RC}}

Donde:
- V_c es el voltaje en el condensador en el tiempo t .
- V_f es el voltaje inicial en el condensador.
- R es la resistencia total en el circuito.
- C es la capacitancia del condensador.
- t es el tiempo transcurrido.

Primero, necesitamos calcular la resistencia total en el circuito. Dado que las resistencias están en paralelo, podemos calcular la resistencia total usando la fórmula:

\frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2}

Donde R_1 = 10k\Omega = 10,000\Omega y R_2 = 330\Omega . Calculando R_{total} :

\frac{1}{R_{total}} = \frac{1}{10,000\Omega} + \frac{1}{330\Omega}
\frac{1}{R_{total}} = 0.0001 + 0.00303
R_{total} = \frac{1}{0.00313}
R_{total} \approx 318.47\Omega

Ahora, con R_{total} y la capacitancia C = 470\mu F = 0.00047 F , y el voltaje inicial V_f = 7V , podemos usar la fórmula de descarga del condensador para resolver el problema. Vamos a calcular el tiempo t cuando el voltaje en el condensador V_c = 0V .

0V = 7V \cdot e^{-\frac{t}{318.47\Omega \cdot 0.00047 F}}
e^{-\frac{t}{150.0151}} = 0
-\frac{t}{150.0151} = \ln(0)
\text{No hay solución real}

El condensador nunca se descargará completamente a 0V en este circuito, ya que requeriría un tiempo infinito. La descarga será exponencial pero nunca alcanzará completamente 0V.

**Respuesta:** El condensador no se descargará completamente a 0V en este circuito.

We plan to test whether the mean mRNA expression level differs between two strains of yeast, for each of 8,000 genes. We will measure the expression levels of each gene, in n samples of strain 1 and m samples of strain 2. We plan to compute a P-value for each gene, using an unpaired two-sample t-test for each gene (the particular type of test does not matter). a) What are the null hypotheses in these tests (in words)? [2] b) If, in fact, the two strains are identical, how many of these tests do we expect to produce a P-value exceeding 1/4? [2]
