power formula class 10
Answers
Answer:
SI unit of power is J/s. SI unit of Power used is Watt. Therefore, Work(W) = mgh = 5 x 8 x 10 = 400J.
Explanation:
The capacity to do work is termed as Energy. The Energy expended to do work in unit time is termed as Power. It is represented as P.
Power Formula is articulated as,
or,
Where,
The Energy Consumed to do work = E
Work done = W
Time taken= t
In any electrical circuit, the power is computed making use of these three formulas
In regards to Voltage and current, it is articulated as
In regards to current and resistance, it is articulated as
In regards to voltage and resistance, it is articulated as
Where,
Voltage applied across the two ends =V,
Current flowing in the circuit = I and
Resistance = R.
The Power Formula is made use of to compute the Power, Resistance, Voltage or current in any electrical circuit. It is articulated in watts
Answer:
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.
In SI base units: kg⋅m2⋅s−3
Derivations from other quantities: P = E/t; P = F·v; P = V·I; P = T·ω
SI unit: Watt
