The magnetic flux through a circuit of resistance R changes by an amount Delta phi in a time Delta t. Then the total quantity of electric charge Q that passes any point in the circuit during the time Delta t is represented by

Answer»

`Q=(1)/(R ).(DELTA phi)/(Delta t)`
`Q=(Delta phi)/(R )`
`Q=(Delta phi)/(Delta t)`
`Q=R.(Delta phi)/(Delta t)`

Solution :INDUCED emf is given by `|V|=(Delta phi)/(Delta t)`
`rArr` current `(i)=(Q)/(Delta t)=(Delta phi)/(Delta t)xx(1)/(R ) ""` [where Q is total charge in time `Delta t`]
`rArr Q=(Delta phi)/(R )`
