An iron designed for use at 120 V and 5.0 A is connected to a power source of 240 V. Calculate the current the iron will draw at the higher potential.
State what will happen to the iron.

please add the formula.​

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
