Question

a 50c charge through a resistor and transfers 100j of energy. what is the potential difference across the resistor

Answer 1

Answer:

An electron volt is the energy given to a fundamental charge accelerated through a potential difference of 1 V. In equation form, 1 eV=(1.60×10-19C)(1V)=(1.60×10-19C)(1J/C)=1.60×10-19J. 1 eV = ( 1.60 × 10 -19 C ) ( 1 V ) = ( 1.60 × 10 -19 C ) ( 1 J / C ) = 1.60 × 10 -19 J.
