WebApr 7, 2024 · Abstract. Voltage regulators provide a constant voltage for a circuit to work. Linear voltage regulators are studied in this chapter. In linear voltage regulators, the transistor is operated in the linear region. Power dissipated in the transistor decreases the efficiency of these type of regulators. WebPower [ P = V x I ] = 24 x 2 = 48W. Power within an electrical circuit is only present when BOTH voltage and current are present. For example, in an open-circuit condition, voltage is present but there is no current flow I = 0 (zero), therefore V*0 is 0 so the power dissipated within the circuit must also be 0.
