Resistor Wattage In Series And Parallel. The power dissipation starts with heat rise in temperature and the wattage also increases. An interesting rule for total power versus individual power is that it is additive for any configuration of the circuit.
Power is a measure of the rate of work and since power dissipated must equal the total power applied by the source s as per the law of conservation of energy in physics. The resistance of r1 is 10 ω and the resistance of r2 is 40 ω. 1 watt in parallel and achieve 2 watts and 10k resistance.
Typically from the temperature above 100 c high wattage resistors are preferred.
Using the current divider formula calculate currents i1 and i2. The electrons passing though two equal resistors in parallel will have two paths to travel at the same time and 50 will pass though each resistor effectively doubling the power rating of the equivalent resistor. Series parallel series parallel or otherwise. Power is a measure of the rate of work and since power dissipated must equal the total power applied by the source s as per the law of conservation of energy in physics.
