Basic electrical engineering
Marks: 100



Instructions for the students :
1)All ques. are compulsory .
2)"Long ans kind ques. (LAQ)" is a supply kind ques. of 20 marks
which requires a typical ans of about 60-80 lines in about 32-40 minutes.
3)"Short ans kind ques. (SAQ)" is a supply kind ques. of five marks
which requires a typical ans of about 15~20 lines in about 08-10 minutes.
4)Use of a non-progra~mable kind of scientific calculator is allowed.
5)Draw neat diagra~s wherever necessary.
6)Assume suita,ble data if necessary .



1)a)Define.volt, current and resistance. State their units.
Find:
b)i) Total resistance
ii) Total current
iii) Voltage drops across every resistance
iv) Power consumed by every
v) Total power
if 4 resistances of 10Q, 20Q, 35Q and 50Q are connected in
series and supply voltage is 400V DC. [marks 5]

c))A parallel circuit contains resistance of 100Q, 60Q, 120Q and 80Q.
The combination is connected across 240 volts. obtain the currents
in every resistance and the power consumed by every. [marks 5]

d)Find the current in every branch of a parallel circuit having 10Q,
25Q, and 20Q, The total current in eight Amp. [marks 5]
