Given information
A huge 4.0-F capacitor has enough stored energy to heat
2.8 kg of water from 21°C to 95°C. It is required to calculate the potential
difference across the plates.
Step-by-step explanation
Step 1.
Capacitance, C=4.0F
Mass of water, m= 2.8kg
Temperature difference, ∆T=(95-21)=74℃.
From the law of conservation of energy,
The potential energy= heat energy absorbed by the water
c= specific heat of water= 4186 J/kg ℃
Therefore,
