Question

a walkman uses a 4.5 v battery. how much resistance is in the circuit if it uses a current of 0.13a?
answer
check
what are the units for your answer?
select one:
ohms
volts
amps
check

Explanation:

Step1: Recall Ohm's Law formula

Resistance $R = \frac{V}{I}$, where $V=4.5V$, $I=0.13A$.

Step2: Calculate resistance

$R = \frac{4.5}{0.13} \approx 34.62$

Step3: Identify unit of resistance

Resistance is measured in Ohms.

Answer:

Resistance: 34.62
Unit: A. Ohms
