Compare the current at A now to the current at A before with only one bulb. A. The current at A is now twice as large as before. B. The current at A is now larger than before but not twice as large. C. The current at A is the same as before. D.The current at A is now half as large as before. E. The current at A is now smaller than before but not half as large. J. None of these is correct.

Answer 1

Thank you

Anr, I current in a chreust remain always constant when it is a series circut option (E) is connect. Ans. 2 2nd identicle bulb is added in Parallet so if Resistance of I bulb is R then in initial situation current was I- V R and now there are two bulb in Parallele so equrfent Resistance Rp = 1 / 1 & Resistance is half so current will be doubled because I= v= V =2v = 2 RC H23 Cursent is doubled So, curent at A is now twice of the current at A as before option CA2 is conect
