What amount of heat will be generated in a coil of resistance R (ohm) due to a total charge Q (coulomb) passing through it if the current in the coil decreases down to zero halving its value every $$\Delta t$$ second?

A

$$\frac{1}{2}\frac{Q^2 R}{\Delta t}$$

B

$$\frac{Q^2 R}{\Delta t}\ln 2$$

C

$$\frac{1}{2}\frac{Q^2 R}{\Delta t}\ln 2$$

D

$$\frac{1}{4}\frac{Q^2 R}{\Delta t}$$
