# A magnetic lock connected to a 12 V alternating current network consumes 50 W • hour of electricity in 5 seconds.

A magnetic lock connected to a 12 V alternating current network consumes 50 W • hour of electricity in 5 seconds. Determine the power of the lock and the current flowing through the winding.

A magnetic lock connected to a 12 V alternating current network consumes 50 W • hour of electricity in 5 seconds. Determine the power of the lock and the current flowing through the winding
Let us determine the power of the magnetic lock, if in 5 seconds its consumption was 50 W * h:
P = 50 * 60 * 60/5 = 36,000W.
Let’s find the current flowing through the winding of the lock, if the voltage is 12 V:
36000: 12 = 3000 A
Answer: the current flowing through the magnetic lock with a power of 36,000 W is 3,000 A.
