Answer:
Mechanical energy is conserved in the presence of following forces:
a) electrostatic force
b) magnetic force
c) gravitational force
Explanation:
Give data:
potential difference ,
we Know change in potential energy is given as
therefore, change in potential energy U is
let speed of particle is v
from energy conservation theorem
loss of electrical PE = KE gained
solving for v
Mechanical energy is conserved for following forces:
a) electrostatic force
b) magnetic force
c) gravitational force
Answer:
Explanation:
Find the total resistance. R3, R4, R5 are in series so add them up.
They are parellel to R2 so add that up. Then that is in series with R1 so add that up.
V=IR. Rearrange the equation to solve for I (current).
