Question

State Joule's law of heating, Write the mathematical form of this law.
b) 200 J of heat is produced in one second from a resistor of resistance 8. Find the potential difference across the resistor and its power.

Answer 1

Answer:

Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called the Joule's equation of electrical heating. b)The resistance of the filament used in the bulb. A 2.5 kW immersion heater is used to heat wate

Answer 2

Answer:

h= i^2 rt
