Resistor Wattage In Series. The formulae for the total resistance r total is as follows. Series parallel series parallel or otherwise.
By substituting ohm s law v ir into joule s law we get the power dissipated by the first resistor as. The power rating or wattage rating of the resistor mainly depends upon the physical size of the resistor. An interesting rule for total power versus individual power is that it is additive for any configuration of the circuit.
Yes they both are 2 watt rating.
If the size of the resistor is large the power rating would be more and it mostly depends on the surface area of the resistor. The power rating or wattage rating of the resistor mainly depends upon the physical size of the resistor. If the size of the resistor is large the power rating would be more and it mostly depends on the surface area of the resistor. In this video i have explained practically 1.
