About Tier 4 - Tensor
A layered challenge requiring substantial reasoning or technical control.
Difficulty describes the challenge, not the solver. It is a Society guide rather than a formal academic level.
The tier is a Society guide to the amount of reasoning, technical work and insight a problem is expected to require. Your experience may vary depending on the topic and your background.
Half Charged
Electricity & Magnetism / RC Charging - 8-12 min
At time , an initially uncharged capacitor of capacitance is connected in series with a resistor of resistance to an ideal constant DC supply of voltage . The capacitor then charges through the resistor.
How long after connection does the capacitor voltage first reach half of the supply voltage? Treat all components as ideal.
Assumptions
Use an ideal constant DC voltage source, an ideal resistor and capacitor, negligible wire resistance and no leakage or stray inductance. Take the component values as the stated model values.
