PHXII03:CURRENT ELECTRICITY

357163 Two heating coils of resistance \(10\Omega \) and \(20\Omega \) are connected in parallel and connected to a battery of emf 12 \(V\) and internal resistance \(1\Omega \). The power consumed by them are in the ratio

1 \(1:4\)
2 \(1:3\)
3 \(2:1\)
4 \(4:1\)

357164 The charge flowing through a resistance \(R\) varies with time \(t\) as \(Q = at - b{t^2},\) where \(a\) and \(b\) are positive constants. The total heat produced in \(R\) is:

1 \(\frac{{{a^3}R}}{{6b}}\)
2 \(\frac{{{a^3}R}}{{3b}}\)
3 \(\frac{{{a^3}R}}{{2b}}\)
4 \(\frac{{{a^3}R}}{b}\)

PHXII03:CURRENT ELECTRICITY

357165 Assertion :
Two electric bulbs of 50 and \(100\;W\) are given. When connected in series \(50\;W\) bulb glows more but when connected parallel \(100\;W\) bulb glows more.
Reason :
In series combination, power is directly proportional to the resistance of circuit. But in parallel combination, power is inversely proportional to the resistance of the circuit.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
