3. ### Quick question about power lines and E=IxR

Ok so I have read that power lines carry very high voltage to minimize loss through resistance, but when I take a look at the formula E=IxR E=Voltage I=Current R=Resistance Divide both sides to get E/I=R To minimize R we should make the numerator of the quotient smaller, and the...
