Ans :

(i) Demand factor = $\frac{M a x i m u m D e m a n d}{C o n n e c t e d L o a d} = \frac{30}{50} = = 0.6 (A n s)$

(ii) Average Load = $\frac{U n i t s g e n e r a t e d i n o n e y e a r}{H o u r s i n a y e a r} = \frac{(60 x 10^{6})}{(365 x 24)} = 6849.315 k W \approx 6.849315 M W$

$∴$ Load factor = $\frac{A v e r a g e L o a d}{M a x i m u m L o a d} = \frac{6.849315}{30} \approx 0.2283 = 22.83 % (A n s)$

3 State maximum power transfer theorem.

Maximum Power Transfer Theorem :

In electrical engineering, the maximum power transfer theorem states that, to obtain maximum external power from a power source with internal resistance, the resistance of the load must equal the resistance of the source as viewed from its output terminals.

If the switch in the following circuit opens at t = 0, find v(t) for t≥ 0 and the initial energy stored in the capacitor.

Created: 1 year ago | Updated: 4 months ago

Updated: 4 months ago

For t<0, the switch is closed.

Capacitor acts as open to DC.

Voltage across the capacitor,

v(0^-)= {(12||4)×V}÷{(12||4)+6} = 8VFor t=0, the switch is opened,Voltage across the Capacitor cannot change instantaneously,So, v(0^-)= v(0) = 8VAt t>0, The capacitor is discharging.R_th= (12||4) = 3 ohmC= 1/6 FTime constant, Π = R_th×C = 0.5 So, v(t) = v(0)e^-t/Π = 8e^-t/0.5=8e^-2tV (Ans.)
