Questions & Answers about Прибор, которому мы передаём энергию посредством лазера, очень мощный.
How does посредством change the feel of the sentence compared to just using the plain Instrumental case (лазером)?
While the plain Instrumental case (лазером) means 'with a laser' and is perfectly fine for everyday speech, посредством elevates the sentence to a formal, scientific register. It translates more closely to 'by means of' or 'via' and must always be followed by the Genitive case (hence, лазера).
Could we use the other formal compound prepositions from this lesson, like с помощью, instead of посредством?
Yes, с помощью лазера or при помощи лазера would also work perfectly here. They are essentially interchangeable in this context and all require the Genitive case. Посредством sounds slightly more abstract, like 'through the medium of,' whereas the others are literally closer to 'with the help of.'
Why is the relative pronoun которому in the Dative case here?
The case of который is determined by its grammatical role inside its own clause, not the main clause. Here, the verb передавать (to transmit) takes an Accusative direct object for what is being transmitted (энергию) and a Dative indirect object for the receiver (которому, referring back to the device).
What nuance does the prefix пере- add to the verb передаём here?
The base verb is давать (to give). The prefix пере- frequently indicates movement across a space or transferring something from one point to another. In this context, it turns simple 'giving' into 'transmitting' or 'transferring' energy to the device.
