|Plug Types||C, F||D, G|
|Frequency of electrical current||50Hz||50Hz|
In Armenia there's more than one plug type in use.
What type of plug does your appliance have?
In Tanzania there's more than one socket type in use. You may require more than one adaptor.
The voltages found in Armenia (220V) and Tanzania (230V) are not exactly the same, but the difference is tolerable, so you should not need a transformer.
The frequency found in Armenia and Tanzania is exactly the same (50Hz). Timing devices and appliances that use motors will function as expected under this frequency.
