Answer:
(a) τ=2.88 s, (b) q₀= 30.6μC and (c) t=1.434s
Explanation:
A RC circuit is an resistor(R)-capacitor(C) electric circuit.
(a) In a resistor-capacitor circuit, the time constant (τ) can be calculated by:
<em>where R: is the resistence and C: the capacitance of the capacitor</em>
(b) The maximum charge (q₀) is giving by:
<em>where ε: is the voltage across the capacitor</em>
(c) The time (t) that take the charge (q) to build up to 12 μC can be calculated from the next equation:
