Web21 de jun. de 2015 · Because the two resistors are in series, you know that the same current flows through both. Measure the voltage drop across the new resistor, then use Ohm’s law to calculate the current. This same current is flowing through the original resistor, so after you measure the voltage drop across the original resistor, you can use Ohm’s …
Resistors are rated according to their maximum power dissipation. Discrete resistors in solid-state electronic systems are typically rated as 1 ⁄ 10, 1 ⁄ 8, or 1 ⁄ 4 watt. They usually absorb much less than a watt of electrical power and require little attention to their power rating. Ver mais A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
