Neco Model Questions Vol1 2020 Physics Question 45
Practice objective / multiple choice question 45 from the 2020 Neco Model Questions Vol1 Physics examination.
A series RC circuit consists of a 24 V battery, a resistor of 200 Ω and an initially uncharged capacitor. After the switch is closed, the current decays exponentially. It is observed that after 0.50 s the current has fallen to 25 % of its initial value. Determine (a) the capacitance \(C\), (b) the time required for the capacitor to reach 90 % of its maximum charge, and (c) the energy stored in the capacitor at that instant.
