Consider an electromagnet (e. g. in a relay) that is operated at 50 a. if the inductance of the coil is 100 h and the time to switch-off the current is 1 ms, what voltage will be developed across its terminals?

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.
