Question

if your notebook is supplied with 8.9 volts and draws 3.6 amps of current, what is its resistance?
answer
check
what are the units for your answer?
select one:
ohms
amps
volts

Explanation:

Step1: Recall Ohm's Law

Ohm's Law states that \( V = IR \), where \( V \) is voltage (in volts), \( I \) is current (in amps), and \( R \) is resistance (in ohms). To find resistance, we rearrange the formula to \( R=\frac{V}{I} \).

Step2: Substitute the given values

We are given \( V = 8.9 \) volts and \( I = 3.6 \) amps. Substitute these into the formula: \( R=\frac{8.9}{3.6} \).

Step3: Calculate the value

Perform the division: \( \frac{8.9}{3.6}\approx2.47 \) (rounded to two decimal places).

Answer:

The resistance is approximately \( 2.47 \) ohms.
