Question

a walkman uses a standard 1.5 v battery. how much resistance is in the circuit if it uses a current of 0.01a?

Explanation:

Step1: Recall Ohm's Law

Ohm's Law is \(V = IR\), where \(V\) is voltage, \(I\) is current, and \(R\) is resistance. We need to solve for \(R\), so we can rewrite the formula as \(R=\frac{V}{I}\).

Step2: Substitute the given values

Given \(V = 1.5\space V\) and \(I=0.01\space A\). Substitute these into the formula \(R=\frac{V}{I}\), so \(R=\frac{1.5}{0.01}\).

Step3: Calculate the value of \(R\)

\(\frac{1.5}{0.01}=150\)

Answer:

\(150\space\Omega\)
