Question 18

A constant potential difference V V\,V is applied across a resistor of resistance R R\,R for a time interval ttt.

Which equation gives the energy E E\,E transferred by the resistor?

A

E=VRtE = \frac{V R}{t}E=tVR​

B

E=V2tRE = \frac{V^2 t}{R}E=RV2t​

C

E=R2tVE = \frac{R^2 t}{V}E=VR2t​

D

E=VR2tE = V R^2 tE=VR2t
