An engineer attempts to build a remotely actuated door lock for asecurity operation. The door is powered by an electromagnetic actuator whose coil can be modeled as a 500Ω resistor .The actuator requires a minimum of 100mA of current for reliable operations.

a) The engineer attempts to power the actuator with a voltagesource and simple switch located 50m from the door through a pairof thin, nearly invisible wires having a resistance of 20 Ωper meter of length.What value of voltage will the engineer requirein order to properly operates the actuator?

b) What safety problem might the engineer encounter in attempt in gto implement this design?

c) Design an improved version of the circuit using a BJT inverterlocated at the site of the actuator. What is the maximum voltage-source value required any where in the system?
