Question

State one advantage and one disadvantage of using thicker wire in the overhead power lines.

Answer 1

HEY MATE WE USE THICKER WIRE IN OBERHEAD POWER LINES BECAUSE RESISTANCE IS INVERSELY PROPORTIONAL TO THE AREA OF CROSS SECTION ,

SO IF AREA OF CROSS SECTION IS MORE THERE WILL BE LOW RESISTANCE AND LESS POWER LOSS.

THANKS.

Answer 2

Answer:

Advantages:

⇒ The resistance of the transmission wire is lowered by making the wire thicker. Thicker wires have larger cross-sectional areas and therefore lower resistance. The low resistance property of the overhead lines can actually be "seen".

Disadvantages:

⇒Less flexible. This makes it harder to install and harder to work with in         general.

⇒Bigger, which means it might not fit thru some small holes or tight places.

Hope it Would be Helpful!!!

Thank YOU!!!
