Ohm's Law
Current = voltage/resistance
Mathematical formula are the algebraic expressions which help calculating easily and mathematically instead of going deep and using steps.
As the name implies, resistance resists current. In the mathematical formula, where E is electromotive force (voltage):- I = E/R If you increase the value of R (resistance), then the value of I (current) decreases.
The formula for calculating resistance in ohms (Ω) is given by Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I). Mathematically, this is expressed as R = V/I, where R is resistance in ohms, V is voltage in volts, and I is current in amperes. This relationship helps to determine how much resistance is present in an electrical circuit.
Current, voltage and resistance are related by the Ohm's law formula which states that current is directly proportional to the applied voltage and inversely proportional to the resistance at a constant temperature. Stated mathematically: I = E/R where I = current in amperes, abbreviated to A E = voltage in volts, abbreviated to V R = resistance in ohms, usually signified by the Greek omega Ω
Resistance(Ohms)= Voltage(volts)/Current (Ampheres) -X
To find the current in the circuit, you can use the formula: Power = Current^2 * Resistance. Given the values, you can rearrange the formula to solve for current: Current = sqrt(Power / Resistance). Plugging in the values, you get Current = sqrt(2 / 30) which simplifies to approximately 0.27 amperes.
The relationship between power, voltage, and current can be expressed mathematically using the formula: Power Voltage x Current. This formula shows that power is directly proportional to both voltage and current. In other words, an increase in either voltage or current will result in an increase in power.
Yes, that's correct. Ohm's law is a fundamental principle in electrical circuits that states the relationship between current (I), voltage (V), and resistance (R) in a circuit. Mathematically, Ohm's law is represented by the formula: V = I * R, where V is voltage, I is current, and R is resistance.
The formula for calculating current in a circuit when given the values of power and resistance is i p/a.
The maximum voltage formula for a circuit is V I R, where V is the voltage, I is the current, and R is the resistance.
The formula for calculating resistance in an electrical circuit is R V/I, where R is the resistance, V is the voltage, and I is the current.
