Answer:
I = 5.0 A V=0
Explanation:
Assuming that the ammeter is an ideal one (which means that the internal resistance is negligible compared with other resistors in the circuit), as the voltage through the capacitor can't change instantaneously, just after the switch is closed, will behave like a short, so applying Ohm's law, the current in the circuit will be as follows:
![I =\frac{V}{R} = \frac{10 V}{2.0 \Omega} = 5.0 A](https://tex.z-dn.net/?f=I%20%3D%5Cfrac%7BV%7D%7BR%7D%20%3D%20%5Cfrac%7B10%20V%7D%7B2.0%20%5COmega%7D%20%20%3D%205.0%20A)
As the voltage in the capacitor, can't change instantaneously, assuming an ideal voltmeter (infinite resistance) , the lecture on the voltmeter across the capacitor will be just 0.
As time goes by, the voltage measured will follow the following equation:
![V = V0*( 1-e^{-\frac{t}{R*C}} )](https://tex.z-dn.net/?f=V%20%3D%20V0%2A%28%201-e%5E%7B-%5Cfrac%7Bt%7D%7BR%2AC%7D%7D%20%29)
We see that when t=0, V=0.

Answer:
Look at the load capacity chart in the cab
Explanation:
A crane can be defined as a large, tall metallic machine or equipment that is designed with a long horizontal arm (jib) used for the lifting and movement of very heavy objects through the air. They're usually designed to be operated by a human operator, who typically uses a remote controller and a beam to control the direction of movement of the crane.
Due to the fact that cranes are used for lifting and moving very heavy objects, they are powered by an internal combustion engine and electric motors.
Furthermore, all cranes have the maximum capacity of load they're able to lift at a particular point in time. In order to determine the rated or gross capacity of a crane and maintain safe operation, it is important to check its load capacity chart. The actual load a crane can lift is its net capacity and it must not be exceeded at any time, so as to avoid structural failure or overturning of the crane.
Hence, the best way to find the load capacity of a crane is to look at the load capacity chart in the cab.
Explanation:
To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.
