In the circuits shown below, the readings of the voltmeter and the ammeter will be

Q. For three circuits, shown here



the same two resistors R₁ and R₂ have been connected in parallel in all the circuits but the voltmeter and the ammeter have been connected in three different positions. The relation between the three voltmeter and ammeter readings would be :
(1) V₁ = V₂ = V₃ and I₁ = I₂ = I₃
(2) V₁ ≠ V₂ ≠ V₃ and I₁ = I₂ = I₃
(3) V₁ = V₂ = V₃ and I₁ ≠ I₂ ≠ I₃
(4) V₁ ≠ V₂ ≠ V₃ and I₁ ≠ I₂ ≠ I₃

Q. A student using the same two resistors, ammeter, voltmeter and battery, sets up two circuits A and B connecting the two resistors first in series and then in parallel.



If the ammeter and voltmeter readings in the two cases be I₁, I₂ and V₁, V₂ respectively he is likely to observe that :
(1) I₁ = I₂ but V₁ ≠ V₂
(2) I₁ < I₂ but V₁ = V₂
(3) I₁ > I₂ but V₁ = V₂
(4) I₁ = I₂ and V₁ = V₂

Q. In the figure ammeter reads $I_1$ and voltmeter reads $V_1$. Similarly in figure 2, ammeter reads $I_2$ and voltmeter reads $V_2$. Then which of the statements are true?

Q. For verification of Ohm's law, the data obtained are given below :

V (in volt)	0.2	0.4	0.6	0.8	1.0	1.2
I (in ampere)	0.5	1.0	1.5	2.0	2.5	3.0

Plot graph for V against I.

Q.

Two different coils have self-inductance $L_1$ = 8mH and $L_2$ = 2mH respectively. The current in both the coils is increased at a same rate. At a certain instant of time, the power being supplied to both the coils is equal. At that instant, the current, the induced voltage, and the energy stored in $L_1$ and $L_2$ are $I_1$ and $I_2$, $V_1$ and $V_2$, and $W_1$ and $W_2$ respectively. Then
