A watt is defined as a unit of power. It is the work rate when a current of one ampere flows through a conductor with a potential difference of one volt.
To learn how to calculate watts in a circuit by type of current, check out our Watts Amps Calculator.
Get a step-by-step process for calculating volts, amps, watts, and ohms in a circuit.
The calculator does all the work for the tools and produces the result easily and quickly.
Below are the steps to calculate Watts, Amps, Ohms in a circuit. Follow these rules to check power value easily.
- Obtain resistance and voltage values.
- Divide the voltage by the resistance to get the current.
- Multiply the voltage and current to check the power value in watts.
Watt’s equation is power P(w) in watts is equal to the voltage v(v) in volts and multiply the current I(A) in Ampere.Hence the watt’s equation can be written as
P(w)= v(v) *I(A)
In an electrical circuit , a watt is stated as the product of volt and amp
Ohm’s law states that the voltage across the conductor is proportional to the current flowing it
Power is the rate of change of electrical energy per unit time. Its unit is watt.
Voltage is the potential difference between two points on a conductor. Its unit is volt.
Current is the quantity of electrons passing any point in a conductor per unit time. Its unit is ampere.
Resistance is the strength of a wire against the flow of electrons. Its unit is Ohm.
R = V2 /P
R= P / I2
V = √(P* R)
I= v /R
P= I2 * R
R= is the resistance
I=is the current
P=is the power
V= is the voltage
If 150 watt light bulb with 250 volts of electrical potential, then find the current and resistance of the bulb?
Voltage v= 250 v
Power P= 150 w
Current I= p/v
Resistance R =V /I
