Heating power in resistor
Web15 de abr. de 2024 · When the resistor has a current to flow through it, it consumes power and the dissipation of power generates heat. The resistance of a resistor changes when it’s heated up. This effect is called self-heating. In precision measurement applications, the error in sensing element resistance matters. WebThe transistor power oscillator has four transistors (TA1,TA2,T'A1,T'A2) having resistors (R1,R2,R3,R4) in series with their emitters. The alternating base voltage which maintains the oscillation is obtained with a capacitive divider (C3,C4,C5,C'3,C'4,C'5).
