The equation of power is P = v x i for the power dissipated by each resistor
Power dissipation is the process of loss of power in the form of heat due to primary action. Power dissipation is a naturally occurring process. All the resistors that are part of the circuit and have a voltage drop across them will dissipate power. The electrical power gets converted to heat energy, and therefore all the resistors will have a power rating. The power rating is the maximum power that can be dissipated from a resistor without burning out.
Power Dissipated in a Resistor
The equation of power is P = v x i
P = i2 R [ since v = iR]
v is the voltage
i is the current
R is the resistance
The power dissipated in the parallel combination of resistors is higher than the series combination of resistors, provided they are connected to the same voltage source.
The formula to determine the power dissipated is
P = i2R
i is the current.
R is the resistance
The dimensional formula of resistance is
[M1L2T-3I-2].
The resistance of a conductor is directly proportional to its length.
