ELECTRIC charge is called electric CURRENT.\(Current\;\left( I \right) = \frac{{charge\;\left( Q \right)}}{{{\rm{\DELTA }}t}}\)CALCULATION:Given that:Time taken (Δ t) = 1 hour 30 minutes = 3600 + (30 × 60) = 5400 secCurrent (I) = 20 A\(Current\;\left( I \right) = \frac{{charge\;\left( Q \right)}}{{{\rm{\Delta }}t}}\)Charge (Q) = Current (I) × time taken (Δ t) = 20 × 5400 = 108000 = 10.8 × 104 C
