Transmission and Distribution Quiz

Why do we use a.c. for transmission and distribution?

• It transforms voltages up and down easily.

• It increases current for transmission for same power.

• It increases heat loss.

• It increases cost.

Answer explanation

It transforms voltages up and down easily.

Which of the following is a benefit of using a.c. for transmission and distribution?

• Increases lost energy.

• Reduces current down for transmission for same power.

• Increases cost.

• Increases heat loss.

Answer explanation

Using a.c. reduces current for transmission, making it more efficient for the same power.

What is one of the reasons for using a.c. in power transmission?

• Increases heat loss.

• Increases lost energy.

• Reduces heat loss.

• Increases cost.

Answer explanation

Using a.c. in power transmission reduces heat loss, making it a more efficient method of transmitting power.

How does a.c. transmission affect energy loss?

• Increases lost energy.

• Reduces lost energy.

• Increases heat loss.

• Increases cost.

Answer explanation

a.c. transmission reduces lost energy, resulting in lower energy loss compared to other transmission methods.

What is one of the cost-related benefits of using a.c. for transmission and distribution?

• Increases cost.

• Reduces cost.

• Increases heat loss.

• Increases lost energy.

Answer explanation

Using a.c. for transmission and distribution reduces cost by minimizing energy losses during the process.
