Answer:3.54ohms
Explanation: connection in parallel
1/Rt= 1/R1+1/R2+1/R3
1/Rt= 1/16+1/13+1/7
1/Rt= 91+112+208/1456
1/Rt= 411/1456
411Rt= 1456
Rt= 1456/411
Rt= 3.54ohms
According to the current, the charge is 818.18 coulombs.
We need to know about current to solve this problem. Current can be defined as the flow rate of charge through the medium. It can be determined as
I = Q / t
where I is current, Q is charge and t is time.
From the question above, we know that
P = 25 W
V = 110 V
h = 1 hour = 3600 second
Calculate the current
P = V . I
25 = 110 . I
I = 0.23 A
By substituting the given parameters, we can calculate the charge
I = Q / t
0.23 = Q / 3600
Q = 818.18 coulombs
Hence, the charge is 818.18 coulombs.

potential energy because it has the ability to do work
Explanation:
A rock resting high in a cliff is an example of potential energy because it has the ability to do work. This form of energy is called potential energy.
- Energy is defined as the ability to do work. To do work, force must applied using energy to move a body through a particular distance.
- A body at rest is not doing any work. This is the case with potential energy of the body on a high cliff.
- At the state of rest, it is not doing any work.
- The potential energy of this body expresses the ability of such body to do work.
