Each phase of a delta-connected load comprises a resistance of 30Ω and an 80µF capacitor in series.
The load is connected to a 400V, 50Hz, 3-phase supply.
Calculate
(a) the phase current,
(b) the line current,
(c) the total power dissipated and
(d) the kVA rating of the load. Draw the complete phasor diagram for the load.
An electric bulb is rated 220 V and 100 W.When it is operated on 110 V, the power consumed will be. Ans) P=V*I I will be same in both cases so P1=V1*I P2=V2*I Dividing both equati
Average and Instantaneous Acceleration: Average acceleration is explained as the change in velocity over a given time interval. As, The instantaneous acceleration of g
Que: What is an electric current? Answer: From Ohm's Law V = IR amid R being a constant one finds that I = V/R. therefore current is equal to voltage divided by resis
The temp gradient is similar to finding the slope of a line (when in two dimensions) Temp. Gradient= Change in Temp. value/Distance. dT/dx = (T2 - T1)/(X2 - X1)
