Explanation / Answer
Q1) Analogy for electriccurrent: A moving train with severalcompartments. Here,all compartments move together with same velocity ,which is just similar to all electrons moving with same velocity in aconductor. Def ofelectric current: It is time rate at which net charge flowtakes place across any cross section of the given conductor ( I = q / t ) unit: ampere Q2) The charge actually reside ononly one plate of acapacitor. The purpose of other plate is to increasethe capacity of capacitor by the principle of electostatic induction. Q3) In the case of rechargable batteries suchas lead acid accumulators , the elecrical energy stored inthe form ofchemicalenergy. After the usage of eneregy, again the battery can berecharged by supplyingelectrical energy to it. Q4) Charge carriers are electrons: Yes, this statement is truein the case of solid conductors, where only free electrons can move and protons cannot move. However, in the case of electrolytes and dischargethrough gases ( at low pre and high pd) both positive andnegative ions move.
