You measure the power delivered by a battery to be 4.81 W when it is connected in series with two equal resistors. How much power will the same battery deliver if the resistors are now connected in parallel across it?

Alightning strike consists of charge moving from a cloud to the ground . in one particular case, the electrons in a lightning strike are confined to travel within a radius of 1.5 m and to move at a speed of 5.0 x 10 m/s. if the density of electrons in the strike is 10'15 electrons/m what current is carried by the lightning ?
