Answer:
d. 25 ms
Explanation:
- In a RC circuit we call time constant to the product of the resistance times the capacitance, which represents the time when the charge reaches to the 63% of the final value, as follows:
[tex]\tau_{1} = R_{1} *C_{1} = 5 ms (1)[/tex]
- If we have a new circuit with new values for R and C, the time constant will be defined in the same way, as follows:
[tex]\tau_{2} =10* R_{1} *0.5*C_{1} = 5*(R_{1}* C_{1}) = 5* \tau_{1} = 5* 5 ms = 25 ms (2)[/tex]
