 
 <prompt> "Field-effect" na label wey dem dey use describe one kain? Given di last question, write one context wey get di answer. E fit be 1 - 20 sentences. Context: <response>: ```Na two kain transistors dey, we get small difference for how dem dey use for circuit. Bipolar transistor get terminals wey dem label as base, collector, and emitter. Small current wey dey flow for base terminal fit control or switch bigger current between collector and emitter terminals. For field-effect transistor, the terminals dem dey label as gate, source, and drain, and voltage for gate fit control current between source and drain.```
