Question

1. Battery voltage = 12v. the current in the circuit is 0.5A. the resistance R must be 2. A 12 volt battery is connected across resistor, and a current 1.5A flows in the resistor. What is the value of the resistor?

Answer 1

To find the resistance, we have to use the following

$R=\frac{V}{I}$

Then, we replace the values

$R=\frac{12}{1.5}=8$

Hence, the answer is A.
