Resistor Wattage In Series And Parallel. The power dissipation starts with heat rise in temperature and the wattage also increases. The total current to two parallel connected resistors is 3 a.
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. Similarly if you need 10k at 2 watts in parallel you can use two 20k resistors at. In a parallel circuit all of the resistor leads on one side of the resistors are connected together and all the leads on the other side are connected together.
Thus the power for the series combination is.
P 2 i 2 r 2 v r 1 r 2 2 r 2. P series dfrac 1 2 dfrac v 2 r. Similarly if you need 10k at 2 watts in parallel you can use two 20k resistors at. Now if the two resistors are connected in series the equivalent resistance is r eq 2r.
