A 55W light bulb will allow 0.5A to flow through it. If the outlet provides a potential difference of 110V, how much resistance is provided by the bulb?

resistance = 220 ohms

Explanation: given that

Power P = 55W

Current I = 0.5A

Potential difference V = 110V,

Using the formula

P = IV =V^2/R

55 = 110^2/R

R = 12100/ 55

R = 220 ohms

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
