tips in current electricity!!!!!!!!!!!!!!
1)If a no. of bulbs of same voltage are conn. in series then the bulb wid least power glows more brilliantly
2)In the above case if these are conn. in parallel bulb wid greatest power glows more brilliantly
3) The sq. of current capacity of a fuse wire is dir. prop. to cube of radius of filament and current capacity is independent of length of tube
4)greater the power of bulb , greater is current capacity
5)greater the power of the bulb lesser is its resistence and thicker is the filament
6) A fuse wire shld hav high resistivity and low melting point but for heating element it shld hav high resistivity and high m. pt....
heater H1 boils water in time TI and heater H2 boils water in time T2....if both heaters are used simultaneously then time taken.....
1)In parallel
1/T = 1/T1 + 1/T2
2)In series
T = T1 + T2
