What is the resistance of a carbon rod at 25.8 ∘C if its resistance is 0.0200 Ω at 0.0 ∘C ?
torisob [31]

0.02020 ohm is the resistance of a carbon rod at 25.8 ∘C if its resistance is 0.0200 Ω at 0.0 ∘C.

<h3 /><h3>What is a resistor?</h3>

A resistor is an electrical component that controls or restricts how much electrical current can pass across a circuit in an electronic device. A specified voltage can be supplied via resistors to an active device like a transistor.

The temperature of the resistor varies based on the variation in the temperature. The equation that describes the relationship between the two of them is:

R = R0[1+ alpha(T-T0)]  where:

R is the new resistance we are looking for

alpha is the temperature coefficient of resistance. For carbon rod, alpha = ₋ 4.8 x 10^{-4}(1/°c)

T0 is the standard temperature =25.8°C

R0 is the resistance at T0 = 0.0200 ohms

T is the temperature at which we want to get R = 0

Substitute in the equation to get R as follows:

R = 0.0200 [1+( ₋ 4.8 x 10^{-4}) (0-25.8)] = 0.02020 ohm

denpristay [2]
Let:
Vx = the pulling component of force
Vy = the lifting component of force

Vy:
Sin(n°) = Vy/hypotenuse
hypotenuse * Sin(n°) = Vy
100N*sin(30°) = Vy
50N = Vy

Vx:
Cos(n°) = Vx/hypotenuse
Hypotenuse * cos(n°) = Vx
100N*cos(30°) =Vx
about 86.6N = Vx

When power and current are known use R = P/I^2 to calculate the resistance.
inna [77]

<h2>\bf{ \underline{Given:- }}</h2>

\sf• \: Power \:( P) = 300  \: watts

\sf• \:  Current \: (I) = 30 \: amps

\\

<h2>\bf{ \underline{To \:  Find:- }}</h2>

\sf• \: The  \: Resistance

\\

\huge\bf{ \underline{Solution :-:- }}

\bf \red {\bigstar{ Formula  \: of \:  Power \: (P) =  \frac{ {I}^{2} }{R}}}

\sf \rightarrow 300= \frac{ {30}^{2} }{ R}

\sf \rightarrow 300 =  \frac{900}{ R}

\rightarrow \sf R = \frac{300}{900}

\rightarrow \sf R =  \frac{1}{3}

\rightarrow \sf R =  0.33

\bf \purple{Hence, \:  the  \: resistance  \: is \:  0.33 \:  Ω \: . }
