Relation Between Watts and Volts: Formula & Differences

Ans: A certain amount of electricity available in a circuit is an example of voltage. The difference in electric potential between two points on a conductor or space, a material, or an electric circuit, are denoted in volts.

Ans: Voltage is the potential difference between two points in space or conductor, It is denoted by volts (v). 

A flow of current is directly proportional to the voltage and inversely proportional to the resistance in the conductor. That means the increase in the voltage causes the increase in current and the increase in resistance causes a decrease in current.

Ans: Voltage is the potential difference between two points in space or conductor, It is denoted by volts (v). 

Voltage is the expression of potential energy (PE). It is generally a difference in voltage between two points. A decrease in voltage is called a voltage drop. The uniform flow of charges through a circuit occurs when a voltage source is connected to the circuit.

Ans: Watt is a unit of power or radiant flux in electromagnetism. 1 watt is the power that works at a rate of 1 joule per second. Power is 1 watt when the rate of consumption of energy is taken as 1 joule per second.

Ans: Watt is the SI unit of power. KW is the most commonly used unit of electrical power. Power is nothing but the energy spent over some time. 

1 Watt = 1 Joule per second (1W = 1 J/s)

1 Kilowatt (KW) is equivalent to 1,000 Watts.

1 kW = 1000 J/s.

Ans: The ability to do work is power. The unit Watt is named after the scientist James Watt. It is the unit of power. A body is said to possess a power of 1 watt if it works at a rate of 1 joule in 1 second. Watt is the SI unit of power.

i1 W= 1 J S-1 

Other units of power are ergs per second, horsepower, metric horsepower or cheval vapour (CV)), and foot-pounds per minute. 

Ans: Voltage is the potential difference between two points in space or conductor, It is denoted by volts (v).

The voltage drop across the electrical load is proportional to the power available to be converted in that load to some other useful form of energy. ... In power distribution systems, a given amount of power can be transmitted with less voltage drop if a higher voltage is used.

Ans: The relation between watt and volt is proportionate. Watt describes the rate of power flow, whereas volt describes the electric potential difference. Accordingly, watt is directly proportional to volt. When the electric power watt increases, the electric potential volt also increases.

Difference between Watts and Volts

Ans. Resistance: Resistance is a property of conductor due to which it resists the flow of electric current through it. A component that is used to resist the flow of electric current in a circuit is called a resistor. In practical application, resistors are used to increase or decrease the electric current.

Ans. When an electric current is supplied to a purely resistive conductor, the energy of the electric current is dissipated entirely in the form of heat and as a result, the resistor gets heated. The heating of resistors because of dissipation of electrical energy is commonly known as the Heating Effect of Electric Current. Some examples are as follows: When electric energy is supplied to an electric bulb, the filament gets heated because of which, it gives light. The heating of an electric bulb happens because of the heating effect of the electric current.

Ans. Electric current generates heat to overcome the resistance offered by the conductor through which it passes. Higher the resistance, the electric current will generate a higher amount of heat. Thus, generation of heat by electric current while passing through a conductor is an inevitable consequence. This heating effect is used in many appliances, such as electric iron, electric heater, electric geyser, etc.

Ans. An electric fuse is used to protect the electric appliances from high voltage if any. Electric fuse is made of metal or alloy of metals, such as aluminium, copper, iron, lead, etc. In the case of flow of higher voltage than specified, fuse wire melts and protects the electric appliances.

Fuse of 1A, 2A, 3A, 5A, 10A, etc., used for domestic purposes.
