3) A one bar electric fire has a power rating of 1000W (1 kW). If the RMS voltage of the mains is 240V, find the RMS value of the current flowing in the fire and the peak values of current and voltage. Due to a fault on the mains supply, the peak voltage surges instantaneously to 1000V…

Extract of sample

In an unloaded circuit there would be no current flow. The fuse would not blow and the power dissapated would be 0 watts. Assuming that the circuit is fully loaded at 1kW, the impedence would be 57.55 ohms, and 4.17 amps. Peak voltage would be 339.36 volts and peak current would be 5.9 amps. At a peak voltage of 1000 volts, the fire would draw 17.38 amps and would blow the 13A fuse.

The slight difference in the measured and calculated values is because of the non-ideal character of an Op-Amp, the connecting wires etc. The moisture component present in the atmosphere, the wiring arrangement of the library, some High Tension (High Voltage) public supply electricity line going around the laboratory also affects the measurements. Sometimes if the connecting wires make a loop then the induction effect also comes in picture.…
