What is is the dimensional formula of electric current?
The dimensional formula of electric current is [I] = [A], where I represents current and A represents ampere.
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 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.
What is the formula for instantaneous current?
The formula for instantaneous current (i) in a circuit is given by Ohm's law: i = V / R, where V is the voltage across the circuit and R is the resistance.
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.
How much current will draw 75000W 400volt at the starting?
At a steady state (when up and running) Watts = Volts x Amps so you just need to solve the equation 75,000 / 400 = ? However, you add the caveat "starting". If your application involves a motor, for example, the starting current will be higher than the steady state current. One rule of thumb says the starting current may be as high as 6 times the running current. This higher current starts high and then decreases as the motor comes up to speed.
What is the dimensional formula of current density?
The dimensional formula of current density (J) is derived from the definition of current density as current per unit area. Current (I) has a dimensional formula of ([I]), and area (A) has a dimensional formula of ([L^2]). Therefore, the dimensional formula of current density is ([J] = [I][L^{-2}] = [I][L^{-2}]).
What is is the dimensional formula of electric current?
The dimensional formula of electric current is [I] = [A], where I represents current and A represents ampere.
What is starting current?
A starting current is the first current and power produced by a machines engine or electrical device. The starting current is used to determine the engines natural strength.
What is the formula for current ratio?
current ratio = current asset divided by current liability
What is the ac motor starting current?
what is the starting current of 2ton window ac voltas
How do you get a current ratio?
Formula for current ratio is as follows: Current ratio = Current assets / current liabilities
How do you calculate voltage drop for starting motor current and how to get the starting pf?
How do you calculate voltage drop for starting motor current
What is the starting current value compared to full load current?
The starting current of any electrical equipment which is 6 times more than that of the full load current. ex: full load current = 5 A the starting current will be 5*6 = 30 A.
How much starting current and running current will take for a 0.75KW 1 phase 220v motor pull?
A 0.75 kW (750 W) single-phase motor operating at 220 V will typically have a full-load running current of about 3.4 A, calculated using the formula ( I = \frac{P}{V} ) (where ( P ) is power in watts and ( V ) is voltage). The starting current, or inrush current, can be significantly higher, often ranging from 4 to 7 times the running current, depending on the motor type and load conditions. Therefore, the starting current could be approximately 13.6 A to 23.8 A.
What formula would you use for current?
=sum(current/4*)
How is the full load current different to the starting current- is the full load current higher or lower than the starting current?
While starting a motor from standstill to its rated speed, the motor has to overcome the inertia and generate enough torque to over come it. In the process the motor takes higher current during the starting. Once started and set in motion the current reduces ti its normal value. Full load current is lower than the starting current normally.
