Steady state is reached with S open. S is closed at t = 0. What is value of the current I at t = 0.?
- 1 A
- 2 A
- 3 A
- 4 A
Correct

Under steady state condition i.e. at t < 0

Capacitor will behave as open circuit at steady state so $V_{\infty }=V_{R2\Omega}=4\times 2=8$ At t > 0 is circuit

Using super position theorem

I = $I_{1}+I_{2}$

Where ,

$I_{1}$ = Current due to 4A source

Where , $V_{\infty}=8V$ is short circuit

$I_{2}$ = Current due to $V_{\infty}=8V$

When 4A is open circuit

$\frac{4\times 2}{2+2}=\frac{8}{2+2}$ = 4A

According to question Number of poles of alternator = 10

Synchronous speed of alternator = Synchronous speed of motor

$\frac{120\times f_{g}}{p_{g}}=\frac{120\times f_{m}}{P_{m}}$

$\frac{120\times 25}{10}=\frac{120\times 60}{P_{m}}$

$\therefore P_{m}=24$

Given $\mu _{n}$ = 3800 cm2/v-s; $\mu _{p}$ = 1800 cm2/V-s ni = $2.5\times10^{-3}$ at 300 K.
- 0.0224 s/cm
- 1.025 s/cm
- 2.025 s/cm
- 3.0256 s/cm
Correct

Since n = p = $n_{l}$

= $2.5\times 10^{-3}/cm^{-3}$

Hence $\sigma =nq(\mu _{n}+\mu _{p})$

$(2.5\times 10^{-3})(1.6\times 10^{-19})$

(3800 + 1800) = 0.0224 s / cm

Incorrect

Since n = p = $n_{l}$

= $2.5\times 10^{-3}/cm^{-3}$

Hence $\sigma =nq(\mu _{n}+\mu _{p})$

$(2.5\times 10^{-3})(1.6\times 10^{-19})$
