 
 <prompt> Wetin be di kain electrical force wey dey happun for field-effect transistor? Based on di question wey dey above, write one context wey get di answer. E fit be 1 - 20 sentences. Context: <response>: Dey get two kain transistors wey get small small difference for how dem dey use for circuit. Bipolar transistor get terminals wey dem dey call 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 dey labeled as gate, source, and drain, and voltage for gate fit control current between source and drain.
