Expert Solution & Answer
Check Mark
To determine

To prove: 1.00 Wb is equal to 1.00 Vs

Explanation of Solution

Given data:

The value of fluxis 1.00 Wb.

Formula used:

The magnitude of induced emf in a coil is expressed as,

ε=|NΔΦMΔt|

Here, N is the number of turns in the coil, t is the time, and ΦM is the magnetic flux.

Explanation:

Recall the expression for the magnitude of induced emf in the coil.

ε=|NΔΦMΔt|

Rearrange for ΔΦM.

ΔΦM=ε(Δt)N

For 1 turn, N=1.

Substitute 1 for N

ΔΦM=ε(Δt)1=ε(Δt)

Write the unitsof ΔΦM, ε, and Δt.

The unit of ε is volt, and Δt is sec.

Substitute 1.00 V for ε, 1.00 Wb for ΔΦM, and 1.00 s for Δt

1.00 Wb=(1.00 V)(1.00 s)=1.00 Vs

Conclusion:

1.00 Wb is equal to 1.00 Vs.
