Answer to Question #129473 in Electricity and Magnetism for Titomi

Question

Please, how do I find the maximum emf produced in the cycle?

Answer 1

If you already have the emf as a function of time, for example:

$$U(t) = 20\sin(250t)\space[V]$$

then the maximum emf produced in the cycle is equal to $20V$. In general it has form:

$$U(t) = U_0\sin(\omega t+\phi_0)$$

where $U_0$ is the maximum emf produced in the cycle.

If you don't have such expression, then all depends on the particular circuit.
