Apologies for all the noobie questions, I just wanna do this right, thanks everyone
After you purchase your bitcoins from an exchange then you just need to withdraw those coins to your electrum wallet. It is very simple but you need to pay a small transaction fee to withdraw or send those coins to you electrum address.
You need to be very careful to use your correct address to withdraw your coins because if you send to wrong address then you can't get back those coins. Since you're a new first send a small amount to your electrum address and see how it works then you can send bigger amounts.
