Question

It is better to send 10,000 kw of electric power long distance at 10,000V rather than at 220V because
1)there is less heating in the transmission wires
2)the resistance of wire is less at high voltage
3)more current is transmitted at high voltage
4)the insulation is more effective at high voltage

Answer 1

Answer:

3

Explanation:

because V=IR

that shows V is directly proportional to I and R

Answer 2

Answer: 3

ExplanationV=IR

If potential is more then the flow of current flow is also more
