Final answer:
The time it takes to charge a capacitor in an RC circuit to 60% of its maximum value can be calculated using the equation V = V0(1 - e^(-t/T)). Given the values of C, the time constant, and the desired voltage, we can solve for t to find the charging time.
Step-by-step explanation:
The time constant for an RC circuit is given by the equation T = RC. In this case, the capacitance (C) is 3.00 mF and the time constant is the same as that of the RL circuit, so we can equate the time constant for both circuits. Let's consider the RC circuit. To charge the capacitor to 60% of its maximum value, we can use the formula V = V0(1 - e^(-t/T)), where V0 is the maximum voltage across the capacitor, V is the voltage at any time t, and T is the time constant.
Since we know the time constant T and the desired voltage V, we can rearrange the equation to solve for t. For example, if V = 0.60V0, the equation becomes 0.60V0 = V0(1 - e^(-t/T)). Solving for t, we find that it will take approximately 0.510 T to charge the capacitor to 60% of its maximum value.
