State two characteristics of a fuse wire.
What are the disadvantages of ring circuit .
what are the advantages of the tree circuit.
a cell supplies a current of 1.2A through two 2 ohm resistors connected in parallel.When the resistors are connected in series,it supplies a current of 0.4 A.calculate the internal resistance and e.m.f. of the cell
very important
two electric lamps of 100W and 25W respectively are connected in parallel to a supply voltage of 200V CALCULATE TOTAL CURRENT FLOWING THROUGH THE CIRCUIT.
what is the difference between power circuit and lighting circuit ?
tree and ring system of household wiring
why can't a fuse be connected in the neutral wire??????
Why is the filament of the electric iron put between mica sheets?
On what factors does the resistance of conductor depend?
Why it is necessary to have an earth wire installed in a power circuit but not in a lighting circuit?
What are catridge type fuses? Why must T1 be connected to the live wire and T2 connected to the neutral wire?
what is difference b/w tree system and ring system
STATE JOULE'S LAW OF HEAT.
two fuse wires of the same length are rated 5A and 20A. Which of the two fuse wires are thicker and why?
Calculate the current through a 60 W lamp rated for 250V .If the line voltage falls to 200V, how is the power consumed by the bulb affected ?
