Answer:
It is connected in series with the circuit
Explanation:
This is because to measure the current in the circuit, the current in the circuit has to flow through the ammeter. As such, the ammeter must be connected in series with the circuit so as to measure the current flowing through the circuit.
So, to measure the current flowing through a circuit with an ammeter, the ammeter must be connected in series with the circuit.
So power is considered as the rate of doing work. Base on the problem given, my analysis is that the machine who finish the work faster is machine C. Therefore, in order to finish the same amount of work in a short period of time you are going to expend the most power. My answer is Machine C.
Given: Mass m = 400 Kg; Height h = 3 m; g = 10 m/s²
Required: Work = ?
Formula: Work = Force x distance F = ma a = g F = mg
W = fd
W = mgh
W = (400 Kg)(10 m/s²)( 3 m)
W = 12,000 Kg.m²/s²
W = 12,000 J
