calculate the potential difference across a 25 - ω resistor if a 0.3 - a current is flowing through it.
calculate the potential difference across a 25 - ω resistor if a 0.3 - a current is flowing through it.
Answer
Answer:
7.5
Explanation:
Step1: Recall Ohm's law
$V = IR$
Step2: Substitute values
$V=0.3\times25$
Step3: Calculate result
$V = 7.5$
