Answer:
P = IV
Ohms law gives voltage as the product of current and resistance i.e.
V =IR
Replacing this in the previous equation gives
P= I(IR) = I^2R
Explanation:
applying ohms law V=IR
Explanation for the following formula: P = I²R
Ohms law states the relation between voltage as the product of current and resistance.
V =IR
From ohms law we deduce the power
p = IV or
⇒P= I(IR)
⇒P = I²R
Ohm's regulation states that the voltage throughout a conductor is at once proportional to the cutting-edge flowing through it, furnished all physical situations and temperatures continue to be steady.
Ohm's law permits you to decide characteristics of a circuit, together with how a whole lot cutting-edge is flowing thru it, in case you know the voltage of the battery in the circuit and what sort of resistance is inside the circuit.
The SI unit of electric resistance is the ohm.Units are treated like everyday English nouns. as a consequence the names of all devices start with a decrease-case letter, except at the start of a sentence or in capitalized material together with a title.
