In the previous question which lamp will glow more brightly when they are in connected in series ?

Two tungsten lamps A and B of resistances R_(1) and R_(2) respectively are connected in a circuit of negligible internal resistance, if R_(1) gt R_(2) (i) The lamp A will glow brightly if lamps are connected in series (ii) the lamb A will glow brightly if lamps are connected in parallel (iii) the lamp B will glow brightly if lamps are connected in series. (iv) the lamb B will glow brightly if lamps are connected in parallel

Two lamps have resistance r and R , R being greater than r . If they are connected in paralled in an electric circuit, then

Two resistance R1 and R2 connected in parallel, this equivalent resistance is.

An ammeter and a voltmeter of resistance R are connected in series to an electric cell of negligible internal resistance . Their readings are A and V respectively . If another resistance R is connected in prallel with voltmeter

The resultant resistance of n wires each of resistance r ohms is R, when they are connected in parallel. When these n resistances are connected in series, the resultant resistance will be
