Recall that to compute for the emf of a circuit given current and inductance, we must recall that 

where I is the current (A), M is the mutual inductance (h), and t is the time (ms). Since the current must not exceed 80.0 V, we have



From this, we see that it must take at least 0.35 ms so it doesn't exceed 80 V.
Answer: 0.35 ms
 
        
        
        
Answer:
electrical energy sometimes.
Explanation:
125.0m 
300 degree Fahrenheit
 
        
             
        
        
        
Answer:
mu=12Tm^2
Explanation:
the magnetic moment mu of a single loop is given by:

where I is the current, B is the magnetic field and A is the area of the loop. By replacing we obtain:
