Study the circuit shown in which two resistors X and Y of resistances 3 Ω and 6 Ω respectively are joined in series with a battery of 2 V.
(I) Draw a circuit diagram showing the above two resistors X and Y joined in parallel with same battery and same ammeter and voltmeter. [1]
(II) In which combination of resistors will the (i) potential difference across X and Y and (ii) current through X and Y, be the same ? [1]
(III) (a) Find the current drawn from the battery by the series combination of the two resistors (X and Y). [2]
Solution
(I) Circuit diagram: 3Ω and 6Ω resistors in parallel connected with a voltmeter, an ammeter and a 2V cell (or Any other way)
(II) (i) in parallel combination.
(ii) in series combination.
(III) (a) Resistance R = 3Ω + 6Ω = 9Ω
V = 2V
I = V/R = 2V/9Ω = 0.22 A
