Question

200 joule it is produced in one second form a resistor of resistance 8 ohm find the potential difference the resistor and its power​

Answer 1

Answer:

The resistor uses 200J in one second;

therefore P=200J/1s;

P=200W;

Since P=V^2/R,

V=sqrt(P*R);

V=sqrt(200*8)

=sqrt(1600)

=40V;

Explanation:

Answer 2

Aɴꜱᴡᴇʀ

$\red{\tt{\therefore \: Potential \: Difference \: across \: Resistor \: is \: 31.62 \: Volts}}$

Heat Energy (H) = 200 J

Resistance (R) = 5 ohm

Time (t) = 1s

Use formula for Heat Energy :

$\begin{lgathered}\dashrightarrow \boxed{\sf{H \: = \: \dfrac{V^2}{R}t}} \\ \\ \dashrightarrow \tt{200 \: = \: \dfrac{V^2}{5} \: \times \: 1} \\ \\ \dashrightarrow \tt{V^2 \: = \: 200 \: \times \: 5} \\ \\ \dashrightarrow \tt{V^2 \: = \: 1000} \\ \\ \dashrightarrow \tt{V \: = \: \sqrt{1000}} \\ \\ \dashrightarrow \tt{V \: = \: 31.62} \\ \\ \pink{\sf{\therefore \: Potential \: Difference \: across \: Resistor \: is \: 31.62 \: Volts}}\end{lgathered}$
