Given two different resistances, how does the rate of joule heating in them differ if they are connected to a fixed voltage sour
1 answer:
In series combination less rate of joule hating should be observed as compared to when connected in parallel combination .
Joule heating, also known as resistive, resistance, or Ohmic heating, is the process by which the passage of an electric current through a conductor produces heat.
Joule's first law states that the power of heating generated by an electrical conductor equals the product of its resistance and the square of the current:
When two or more resistors are connected end to end consecutively, they are said to be connected in series combination. The combined resistance of any number of resistances connected in series is equal to the sum of the individual resistances.
When two or more resistances are connected between the same two points, they are said to be connected in parallel combination. The reciprocal of the combined resistance of a number of resistances connected in parallel is equal to the sum of the reciprocals of all the individual resistances.
Rate of joule heating can be calculated by the formula
Power = / R
V = voltage
R = resistance
When both are connected in series than their equivalent resistance will be more as compared to when they are connected in parallel.
Power is inversely related to resistance , if voltage is constant
In series combination less rate of joule hating should be observed as compared to when connected in parallel
