A current of 2A flows through a wire for a minute. Find the amount of charge flown through the wire? If the wire is connected in series to a 9V battery, how much energy would be spend by the battery?

Answer» GIVEN,Current in 2Ω RESISTER = 3APotential ACROSS 2Ω resister V= IR=3×2=6V POTENTIAL is equal in PARALLEL connection.Current flow in 1Ω & 5Ω resister i= RV = 5+16 =1APower dissipate in 5Ω resister =i 2 R=1 2 ×5=5 WPower dissipate in 5Ω resister is 5W
