Two electric bulbs of 100 ohms are used for 8 hours daily. What is the cost of them for 1 day if the rate is 75 paise per unit?

Solutions

Expert Solution

Steps:-

In this question supply voltage is not given so we assume supply voltage is 220 volt and after by Ohm's law we calculate amount of current and after we calculate after it we obtained consumed kwh in one day . and finaly we calculate cost of electricity.concept:- this is is an aptitude question only basic requirement is Ohm's law and definition of one unit which is equal to 1 kwh.

Two identical electric bulbs are connected in series and then to a battery. The third identical bulb then is connected in parallel to the line of first two bulbs. This additional connection will: Increase the illumination produced by bulbs connected in series Decrease the illumination produced by bulbs in series Leave the illumination produced by bulbs in series unchanged It will change illumination somehow, but we need to know the voltage on battery and resistances of bulbs to answer.
