As far as I know Electrum is designed for BitCoin (classic).
it is called bitcoin.
if you see any trailing words it means it is an altcoin. bitcoin classic, bitcoin cash, bitcoin gold, bitcoin silver, bitcoin private, bitcoin blahblah are all altcoins.
and electrum is designed for bitcoin only. anything else which is not in the following links is a fork of electrum and is not by the original team
https://electrum.org/https://github.com/spesmilo/electrumIs there a way to handle BitCoin Cash as well?
this was answered by @TryNinja above, i just want to add that when you see forks of bitcoin like BCH you can most of the times use bitcoin tools (like bitaddress.org or even electrum) to create addresses and receive those coins in.
for example you can create a BCH paper wallet with bitaddress.org and receive bitcoin cash. but for spending you need to download a BCH wallet.
If yes: How do I distingish between these two cryptocurrencies?
the name should be more than obvious. bitcoin is bitcoin and anything that is bitcoin (something here) is not bitcoin.
then it is the links. for example real Electrum link is the one i posted above. anything other than that is not for bitcoin. for example
https://electrum-ltc.org/ is electrum fork for litecoin.
