If you have a light bulb connected to a circuit and you increase the current, what happens to the light bulb and the power (assuming the voltage remains the same)?

a. the light bulb shines brighter and power decreases
b. the light bulb shines brighter and the power increases
c. the light bulb gets dimmer and the power decreases
d. the light bulb gets dimmer and the power increases

The correct answer is Option b.

Explanation:

Power is defined as the amount of work done in a given amount of time. It is also defined as the product of voltage and the current.

Mathematically,

where,

P = power

V = voltage

I = current

As, the voltage remains constant, and if we increase the current flowing through the light bulb, power will also increase because current is directly proportional to the power of the light bulb.

Increase in the power will increase the brightness of the bulb and vice-versa.

Hence, the correct answer is Option b.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
