What is the formula for calculating current in a circuit when given the values of power and resistance, where i p/a?
The formula for calculating current in a circuit when given the values of power and resistance is i p/a.
What is the current in a circuit that has a resistance of 30 ohms and a power of 2 watts?
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.
What is the formula for calculating the power dissipated in a resistor, given the current flowing through it and the resistance value, known as the i2r power?
The formula for calculating the power dissipated in a resistor, known as the i2r power, is P I2 R, where P is the power in watts, I is the current in amperes, and R is the resistance in ohms.
How many millawatts is in a amp?
A micro-amp is a measure of current. Power in Watts is a function of the current and voltage. Impossible to answer your question without knowing the voltage. For example, 1 uA (micro-amp) x 10 Volts = 10 micro-Watts, but 1uA x 1,000.000 Volts = 1Watt.
What is important when measuring power?
To measure power, you need the Voltage, and Current. In the case of AC you need the number of phases, and the power factor. Once you have these, you can find the proper formula.
What is the formula for calculating power if you are given magnetic field?
The formula for calculating power if you are given a magnetic field is sub 43
What is the relationship between power, voltage, and current, and how can it be expressed mathematically using the formula power equals voltage multiplied by current?
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.
Which equation should be used to find current when volts and watts is given to you?
You can use the formula I = P/V, where I is the current in amperes, P is the power in watts, and V is the voltage in volts.
What is the formula for determining power?
power = current x voltage
What is the formula for power in terms of amperes?
Electrical power = current x voltage Current is in amps
