The damage of electrical shock is predominantly due to

Select one:

a. none of these

b. reduced resistance

c. an absence of voltage

d. excess current

A bird can sit harmlessly on a high-voltage wire because

Select one:

a. no potential difference is across the birds feet

b. the net charge on a current-carrying wire is zero

c.

current is inside, not outside, the wire.

d. all of these

Compared to a single lamp connected to a battery, two lamps connected in parallel to the same battery will draw

Select one:

a. the same current

b. less current

c. more current

Explanation / Answer

1)

a. none of these.

The cause of electrical shock is predominantly excess voltage.

2)

a. no potential difference is across the birds feet.

The bird’s feet is not a good conductor.

3)

b. less current                                          

When they are connected in parallel, the current is divided between the 2. So, each get lesser current that a single one.
