ELECTRICITY
1. The transformer has a ratio primary:secondary of 100:10. The transformer is
supplied with 220 VAC.
What is the voltage at Ve?
Is the signal at Ve alternating current (AC) or direct current (DC) ?
Draw the signal at Vs in the graph below:
2. If a device uses 110VAC and consumes 2A, what is the power consumption of the
device ?
What is the unit of measurement for the electrical power of a device?
3. What does the formula represent: U= R.I
4. If I = 1350 mA, what is the value of I in amperes (A)?
5. If U = 117 kV, what is this in volts (V)?
6. You see that a 10A fuse is out of order and you do not have a fuse of the
same rating. What can you do (tick any boxes that could apply):
Replace the fuse with a 16A one
Temporarily use a copper wire
Wait until you have a 10A fuse
Replace the fuse with a 10A relay
7. The power rating of an autoclave is 18 kW. The electrical junction box supplying
this device is 60 meters from the sterilization room.
What section of cable must be used if the autoclave is operating in three
phase 380V (see appendix)?
What type of circuit breaker / protection must be used?

8. The example below is of haemoglobin meter that needs to be cleaned once per
week with a single dose bottle of cleaner. The cleaner bottles come in packages
of 5. That is to say; one package is enough for 5 cleans.
If you must make an order for six months of operation, what is the quantity you
need to order?
