When magnetic flux through a coil is changed, the variation of induced current in the coil with time is as shown in graph. If resistance of coil is $10Ω$ , then the total change in flux of coil will be-

Answer:

2.00

Solution:

Ans (2.00)

Total charge flown = Area under (I - t) curve $= \frac{1}{2} \times 4 \times 0.1 = 0.2$ C

$Δ q = \frac{Δ Q}{R} \Rightarrow Δ Q = R (Δ q) = 10 \times 0.2 = 2$

$Δ Q = 2$ T-m $^{2}$
