Question

How does wireless charging use mutual inductance?

Options

• Perpendicular coil axes always transfer the maximum energy.

• Tightly coupled coils step up or step down voltage.

• Loosely coupled coils transfer energy without physical contact.

• A cooktop coil induces current in cookware.

Answer 1

Wireless charging transfers energy between loosely coupled coils. The transfer occurs without physical contact between the coils.
