Calculating Voltage Resistance And Current
The amount of current in a circuit depends on the amount of voltage and the amount of resistance in the circuit to oppose current flow.
Calculating voltage resistance and current. For this reason the quantities of voltage and resistance are often stated as being between or across two points in a circuit. If a current i should flow through a resistor r the voltage v can be calculated. Calculate power current voltage or resistance. A potential difference voltage across an electrical component is needed to make a current flow through it.
The team of a calculator online provided a simple and efficient tool known as ohms law calculator through which you can readily find out the value of voltage v current i power p and resistance r concerning simple ohm s law formula. For example in a series circuit with 3 resistors of 2 3 and 5 ohms and a voltage of 12 volts the current would be 12 divided by 10 or 1 2 amperes. V v i a r ω. First version of the voltage formula.
Power voltage current resistance p v i r calculator. The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω. Ohm s law can be rewritten in three ways for calculating current resistance and voltage. The power p in watts w is equal to the voltage v in volts v times the current i in amps a.
Simple to use ohm s law calculator. 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. Just enter 2 known values and the calculator will solve for the others. Once you have the current calculate voltage for the individual resistors by multiplying the current by the resistance.
If there is a voltage v across a resistor r a current i flows through it. The power p in watts w is equal to the voltage v in volts v times the current i in amps a. Current voltage and resistance current is the rate of flow of electric charge. I can be calculated.
But we have designed this one especially for dc circuits as well as work for single phase ac circuits without power factor. Ohms law calculator is used to find resistance voltage and current in a circuit. The power p in watts w is equal to the squared voltage v in volts v divided by the resistance r in ohms. The voltage v in volts v is equal to the square root of the power p in watts w times the resistance r in ohms ω.
