Commercial Electrical EnergyAn electrical appliance uses a lot of electric energy when it is operated e.g., geysers heaters etc. The electrical energy consumed is dependent on the time for which a specific appliance of fixed power rating is used. However, the energy used in hour is denoted as `1 kWh=3.6 xx 10^6` joule. This is represented as 1 unit. Different electrical appliance have difference power consumption which is mentioned on the device clearly.Two electric bulbs P and Q having resistances ratio 1 : 2 will consume power in the

12 cells, each of emf `1.5 V` and internal resistance of `0.5 Omega`, are arranged in `m` rows each containing `n` cells connected in series, as shown in the figure.Calculate the values of `n and m` for which this combination would send maximum current through an external resistance of `1.5
A battery of emf E has an internal resistance r. A variable resistance R is connected to the terminals of the battery. A current `i` is drawn from the battery. V is the terminal potential difference. If R alone is gradually reduced to zero, which of the following best describes `i and
Resistance and Resistivity The materials can be classified as conductors, semiconductors and insulators depending on their resistivities, in an increasing order of their values. Metals have low resistivities in the range of `10^(-8)Omegam` to `10^(-6)Omegam`. At the other end are insulators like ceramic, rubber and plastics having resistivities `10^(18)` times greater than metals or more. In between these two are the semiconductors. These however, have resistivities characteristically decreasing with a rise in temperature. The resistivities of semiconductors can be decreased by adding small amount of suitable impurities. This last feature is exploited in use of semiconductors for electronic devices.Commercially produced
