How much work is done when 0.0050 c is moved through a potential difference of 9.0 v? use w = qv?

0.045 J

Explanation:

The work done on a charge moving through a potential difference is given by

where

W is the work done

q is the charge

is the potential difference

In this problem, we have

q = 0.0050 C is the charge

is the potential difference

Using the formula, we find the work done:

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
