Chapter SH, Problem 6.3APP

To determine

To calculate: Resistance in a circuit.

Answer to Problem 6.3APP

Resistance in the circuit is $\underset{\_}{2\Omega }$ .

Explanation of Solution

Given:

Voltage difference = $3.0\text{ V}$

Current = $\text{1}\text{.5 A}$

Formula used:

Current is given by,

  $I=\frac{V}{R}$

where V is voltage difference and R is resistance.

Calculation:

Resistance is calculated as:

  $\begin{array}{l}I=\frac{V}{R}\\ R=\frac{V}{I}\\ R=\frac{3.0\text{ V}}{1.5\text{ A}}\\ R=2\Omega \end{array}$

Conclusion:

Resistance in the circuit is $\underset{\_}{2\Omega }$ .
