dear mrinal thats alternating current , (ac ) used in homes and bulb connection , i think thatswhat u want to know . there are rectifier installed to change the coming dc cuirrent into ac . IN AC...
Be the first one to answer
Since the battery would in parallel to the 8v and internal resistance 1 ohm and the 15 ohm resistance with series, the battery purpose would only have to charge the 8 volt Emf, Hence the current drawn...
The cells are connected in series and the circuit is closed henc if U apply KVL in the loop, U would get, E1 + E2 = iR where R is the internal resistanc of the cells. Hence the potential gets added...
I AGREE TO SHUBHAM it can be anything .NAVJOT if u have any query pl send it to us also check our books on website askiitians
FOR QUES 23 R+R =2R ON BOTH SIDE OF A R+R=2R ON BOTH SIDE OF B RESULTANT OF 2 ARE IN PARALLEL 1/2R+1/2R=1/R R IS OUR ANSWER
FIRST OF ALL THE PICTURE IS NOT CLEAR. PLZZZ SEND next time with good quality for any other queries [lease contact our website askiitians. THANXXXX
i=Asin(wt+fi) A=peak current comparing from your question A=4 I(r m s)=A/2 1/2 I(r m s)=2 3/2 i hope my answer is correct . I hope that u understood. Please contact for any other queries. THANKS AND...
A fuse wire is an electrical instrument used for reducing the damage of electrical appliances when a high current passses into the wire. A fuse wire should have more resistance and a low melting...
dear kavin ohm’s law holds correct for only conducters where resistance have some value , its not hold true for super conducter and diodes also , and 1 more thing – superconducters are the extreme...
1. R2. 4A3. R/3CONsider the point with same potential difference as same point . then redraw the circuit and solve it.
dear pooja you can choose kirchoff law , and it have a wide range of application in every electrical circuits , for example in your household circuits , in any circuit presentation , if there will be...
HI Reema, total resistance R = 3 + (3*6)/(3+6) = 5 ohm emf = 15V current though terminal of battery i = V/R = 15/5 =3A p.d. between terminals = emf – i*(internal resistance) = 15 – 3*3 =15 – 9 = 6V...
dear pawan the power given on bulb is just rated power, the power at which it is recommended for bulb. watt is time less quantity, it will glow till the time you supply 100 watt power , also you can...
The correct answer is 3rd one... As to convert a galvanometer into an ammeter we provide a resistance in parallel with the galvanometer known as shunt... Apply basic ohms law and get d ans
dear ruchendran electropossitive metals are those metals which have extra electrons and they tend to loose electrons and form possitive ions which is stable . so, they will emit electrons for sure ,...
Hii we don’t give answer in regional languages .if you need answers in english then only we can we can help you. For other queries related to IIT JEE you can contact us at 0120-4616500 or you...
By formula, Cd÷Cw=k.so you can find the freshness of a fish .place the fish between two parallel plates, if k is max then the fish is fresh.
electric current means the flow of charges (electron, proton), charges have some magnetic field around them due to the spining and rotation. charges flows from high potential to lower potential...
Resistances are connected inn various ways according to situation. Resistances are connected in series in cases of fuse and stabiizers in order to keep the other appliances safe without damaging....
After just closing the switch at time t=0, I1 = e/2R as the capacitor becomes short circuit. At time t= infinity, the capacitor behaves as an open circuit brach and therfore, I2 = e/3R Hence, I1/I2=...
