In a circuit, where is resistance and is capacitance which of the following has the dimension of time.
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
The current in DC ciruit containing resistance and capacitance is given by, i=i01-e-tRC As the power of e should be dimensionless, the dimensions of RC should be equal to that of time.
