Answer:
The maximum current which can flow through a fuse without melting it, is called its rating. ... If current higher than 8 A flows through the fuse, it would melt and circuit gets broken. ... Hence, fuse acts as a safety device
Because you have to have energy to have work.
Answer:
32 W.
Explanation:
Power: This can be defined as the ratio of energy to time. The S.I unit of power is watt(W). The formula for power is given as,
P = W/t.................... Equation 1
Where P = power, W = work done, t = time.
Given: W = 400 J, t = 10 s.
Substitute into equation 1
P = 400/10
P = 40 W.
If the motors that is choose is 80% efficient,
P' = P(0.8)
Where P' = minimum power
P' = 40(0.8)
P' = 32 W.
