EEE :: Current Electricity
- Three 60 W bulbs are in parallel across the 60 V power line. If one bulb burns open
- Two bulbs of 500 W and 200 W rated at 250 V will have resistance ratio as
- A rheostat differs from potentiometer in the respect that it
- Are the materials having electrical conductivity much less than most of the metals but much greater than that of typical insulators.
- In a series circuit with unequal resistances
- The resistance of a conductor varies inversely as
- A resistance having rating 10 ohms, 10 W is likely to be a
- If the efficiency of a machine is to be high, what should be low?
