When high voltage leads to low current in power transmission system using transformers,how increase in voltage in household circuits from 220 volts makes the current increase damaging the appliances,
I understand the power transmission this way that when a battery of 1.5 volt that can work for maximum 2 hours when connected to a resistor drawing current of 10 amp,its power is vit = 1.5 x 10 x 2 = 30 watt hour,
What i do not understand is how in the power generation system the voltage increases but current decreases and when this is true,
when the voltage of the household supply using 220 volt alternating current supply increases,the current should decrease enabling the appliances work safer in high voltages as the appliances get damaged not by the voltage but by the current that flows through them,
but the opposite happens in household system that is when voltage increases current increases damaging the appliances.
