Power Of Electric Current

How to use ohm s law to determine current.

Power of electric current. An important aspect of any electrical or electronic circuit is the power associated with it. The electric power is divided into two types i e the ac power and the dc power. Current voltage and power. The current electricity tariff exclusive of gst is 21 43 cents per kwh.

832 electric charge is carried by charged particles so an electric current is a flow of charged particles the moving particles are called charge carriers which may be one of several types of. But we have designed this one especially for dc circuits as well as work for single phase ac circuits without power factor. 1 oct 31 dec 2020 inclusive of gst 22 93 cents per kwh. 614 an electric current is said to exist when there is a net flow of electric charge through a region.

It can take the form of a sudden discharge of static electricity such as a lightning bolt or a spark between your finger and a ground light switch. By multiplying the voltage in volts by the current in amps we arrive at an answer in watts let s apply this to a circuit example. Electricity is the flow of electric charge we can describe the flow of electric charge in several ways. These include the quantities current voltage and power.

This fact is used by electrical heaters which consist of a resistor through which current flows. Current i is the rate of flow of charge carriers such as electrons current is usually thought of as moving in the direction of positive charge so from the positive power supply to the negative. Power system operation and market administration fees. This calculator is based on simple ohm s law as we have already shared ohm s law p i v r calculator in which you can also calculate three phase current.

We ve seen the formula for determining the power in an electric circuit. It is found that when a current flows through a resistor electrical energy is converted into heat. A 60 watt lightbulb pulls. Electric current is electric charge in motion.

An electric current is the rate of flow of electric charge past a point. In the above circuit we know we have a battery voltage of 18 volts and a lamp resistance of 3 ω. The centimetre gram second units of current is the electrostatic unit of charge esu per second. Commercial power lines make available about 100 amps to a typical home.

Power voltage current resistance p v i r calculator. Details of the electricity tariffs are available at sp group. One ampere equals 3 10 9 esu per second. The utility of power is measured by the.

Learn the power formula. The electric power is sold regarding joule which is the product of the power in kilowatts and the running time of the machinery in hours.
