What type of circuits is used for wiring system in our home?

Two identical heating elements, each having resistance R, are connected first in series and then in parallel across the same ideal battery. The ratio of heat produced in the parallel arrangement to the series arrangement in the same time is:

Which of the following terms does not represent electrical power in a circuit?

An electric bulb is rated 220 V and 100 W. When it is operated on 110 V, the power consumed will be –

Two conducting wires of the same material and of equal lengths and equal diameters are first connected in series and then parallel in a circuit across the same potential difference. The ratio of heat produced in series and parallel combinations would be –

To detect obstacles in the path man, birds and electronic device uses sensor. If true can you tell name of the sensors used by man, bird, electronic devices.

A cylindrical conductor of length 'l' and uniform area of cross section 'A' has resistance 'R' The area of cross section of another conductor of same material and same resistance but of length '2l' is

KIRCHOFF JUNCTION RUL IS BASED ON CONSERVATION OF CHARGE.

The values of current $I$ flowing in a given resistor for the corresponding values of potential difference $V$ across the resistor are given below –

Plot a graph between $V$ and $I$ and calculate the resistance of that resistor.

In the figure, the voltages are v1(t)=100cos(wt),v2(t)=100cos(wt+π18) and v3(t)=100cos(wt+π36). The circuit is in sinusoidal steady state, and R<<wL.P1,P2,P2 and P3 are the average power outputs. Which one of the following statements is true?
