Radiant electric replace the age old coil with elements below a ceramic or glass surface. They are uniformly abysmal to cook with.
Induction are very different from radiant electric and require cookware of particular materials. They are amazing in some respects and limited in others.
From a glance though both have smooth glassy surfaces that look modern.
I haven't seen a coil hob for years, I think my grandma had one.
The cheapest option apparently called a solid plate hob in Britain. Those coils are inside a ceramic (I think) plate. The cheapest ones cost about £80. They're difficult to damage, so you find them in the cheapest rented apartments (students etc): https://www.currys.co.uk/gbuk/household-appliances/cooking/h...
"Ceramic" hobs refers to the one with heating elements below glass/ceramic. Starts from £110, but it's a bit easier to damage. Many rented homes would have this, since it looks fancy and clean.: https://www.currys.co.uk/gbuk/household-appliances/cooking/h...
