The Answer of The potential applied to a $20 - \Omega$ resistor is $( 60 \mathrm {~V} ) \cos ( 33 t )$. What is the average power consumed in the resistor?

The Potential Applied to A 20−Ω20 - \Omega20−Ω Resistor Is (60 V)cos⁡(33t)( 60 \mathrm {~V} ) \cos ( 33 t )(60 V)cos(33t)

The Potential Applied to A $20 - \Omega$ Resistor Is $( 60 \mathrm {~V} ) \cos ( 33 t )$
