Question

driver relation between power and voltage class 10th ch electricity..​

Answer 1

=================================================

Answer :

P = V I

Explanation :

According to the joule’s law of heating which states that the heat produced is proportional  

• Square of the current
• Resistance of the circuit R
• The time t during which the current flows through the circuit.

Mathematically,

   $H=I^2Rt$

Power is defined as heat per second

$P=\frac{H}{t}\\\\ =>P=\frac{I^2Rt}{t}\\\\ =>P=I^2R\\\\=>P=I(IR)\\\\=>P=IV[We*know *\Omega's *law,V=IR ]\\\\=>P=VI$

Answer 2

Power is directly proportional to voltage or potential difference (volt)

⚡ ⚡ { P = V I } ⚡ ⚡

# Higher the power, more the

voltage and lower the power

,Less the voltage.
