Gwrthydd yw cydran trydanol a ddyluniwyd i wrthod cerrynt trydanol gan gynhyrchu gostyngiad foltedd rhwng ei derfynellau mewn cyfrannedd â'r cerrynt, hynny yw, yn ôl Deddf Ohm:

Gwaith y gwrthydd mewn cylched yw gwrthsyfyll llif y gwefr; gellir cymharu hyn â'r ffordd mae ffrithiant mecanyddol yn gwrthsefyll mudiant. Yn y ddau achos, rhaid gwneud gwaith er mwyn goresgyn y gwrthsafiad, a chanlyniad y gwaith hyn fydd gwres ac felly afradloni'r egni.
