Question

Current in a resistor $R$ uniformly decreases from som value to zero in time $\Delta t$. Total change, that crosses the cross section is $q$. Choose the correct option(s)

• A. Heat generated in the resistance during this process is $\frac{4}{3}\frac{q^{2}R}{\Delta t}$
• B. Heat generated in the resistance during this process is $\frac{2}{3}\frac{q^{2}R}{\Delta t}$
• C. maximum current is $i_0=\frac{2q}{\Delta t}$
• D. maximum current is $i_0=\frac{q}{\Delta t}$

Answer 1

Answer: (A), (C)

The correct options are
A Heat generated in the resistance during this process is $\frac{4}{3}\frac{q^{2}R}{\Delta t}$
C maximum current is $i_0=\frac{2q}{\Delta t}$
