a resistor, of resistance 47 , is damaged when it dissipates a power greater than 0.5W. determine the maximum voltage that can b
harkovskaia [24]

Answer:

<em>The maximum voltage that can be applied without damaging the resistor is 4.85 V</em>

Explanation:

<u>Electric Power in a Resistor</u>

Given a resistor or resistance R connected to a circuit of voltage V carrying a current I. The relation between these three magnitudes is given by Ohm's Law:

V = R.I

The dissipated power P of a resistor can be calculated by the following equation, known as Joule's first law:

P = I^2.R

Solving the first equation for I:

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

Substituting in the second equation:

\displaystyle P=\frac{V^2}{R^2}.R

Simplifying:

\displaystyle P=\frac{V^2}{R}

Solving for V:

V=\sqrt{P.R}

The resistor has a resistance of R=47Ω and can hold a maximum power of P=0.5 W, thus the maximum voltage is:

V=\sqrt{0.5\cdot 47}

V=\sqrt{23.5}

V = 4.85 V

The maximum voltage that can be applied without damaging the resistor is 4.85 V
