Question

What does \[\varepsilon\] represent, and what is its SI unit?

Options

• Self-inductance (coefficient); henry (H)

• Induced EMF (self-induced); volt (V)

• Magnetic flux through one turn; weber (Wb)

• Current through the coil; ampere (A)

Answer 1

\[\varepsilon\] is the EMF induced in the coil itself. EMF is measured in volts (V).
