BEL-NBT: Network And Bridges Trainer
About Product
A complete trainer that enables students to verify core electrical theorems and characterize AC bridges with built-in R, L, C banks and a solder-less proto area. Covers Superposition, Thevenin, Norton, Maximum Power Transfer, Reciprocity, KCL/KVL, and advanced bridges including Hay’s, Schering, Anderson, Owen’s and LC resonance.
