An infinitely long wire carrying a current of 4.5 A is bent at the origin and extends in both the y-direction and x-direction. (In other words, the wire makes a 90 degree angle with the x axis and y axis and has a bend at the origin) Find the magnetic field at the point x = 3 cm and y = 2 cm.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

How does a circuit breaker protect a refrigerator? a. when the current is too high, a metal strip in the fuse melts and opens the circuit. b. when the resistance is too high , a re-settable which opens a circuit c. when the current is too high , a re-settable switch opens the circuit d. when the resistance is too high a metal strip in the fuse melts and opens the circuit
