a simple circuit within a laptop has a single resistor with a resistance of 0.1 ω and requires a current of 50 ma. select the voltage that would allow the computer to function correctly.\n5 v\n50 v\n500 mv\n5 mv
Answer
Explanation:
Step1: Recall Ohm's Law
$V = IR$ (where $V$ is voltage, $I$ is current, $R$ is resistance).
Step2: Convert current to SI - unit
The current $I = 50\ mA=50\times10^{- 3}\ A$, and the resistance $R = 0.1\ \Omega$.
Step3: Calculate the voltage
$V=I\times R=(50\times10^{-3}\ A)\times(0.1\ \Omega)=5\times10^{-3}\ V = 5\ mV$.
Answer:
5 mV
