How do you convert into maximum current if the average current is given?
Presumably you are referring to an a.c. current?If so, then the average value of an a.c. current is zero so, clearly, you cannot determine its maximum value.However, average current is more-usually applied over half a cycle, in which case, for a sinusoidal current, this value is 0.637 Imax. So the maximum current will be the average value, divided by 0.637.
What is internal resistance of battery?
The equivalent resistance you would have to place in series with an ideal battery (which of course does not exist) of the same voltage to get the same behavior (voltage drop with load) as the real battery has. It is a mathematical modeling technique to help in circuit analysis.
What is maximum current?
If you are referring to an a.c. current, then the maximum current is the amplitude of its waveform. For a sinusoidal waveform, the amplitude of an a.c. current is its root-mean-square value, divided by 0.707. For example, an a.c current with an rms value of, say, 10 A will have an amplitude of 14.14 A,
How do you calculate maximum earth fault current?

How many ohms is a 120 volts?
"Volts" is electrical pressure applied to a circuit; whereas, "ohms" is electrical resistance to that pressure. One cannot determine ohms from voltage without knowing either the current (in "amps") or power (in "watts"). A normal 120V household circuit can handle a maximum of 20 amps, so using ohm's law of resistance = voltage / current, the minimum resistance required in a 120V household circuit would be 6 ohms. Any less than 6 ohms will cause the circuit breaker to trip.
What is formula for calculate maximum current?
volts divided by resistance equals maximum amperage (current)
What is the maximum voltage formula for a circuit with a given resistance and current?
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.
Why rheostats have current rating in addition to resistance rating?
A resistor, of which a rheostat is, has a maximum amount of current it can handle. Beyond that value it will start heating up a lot and might burns up. Since, the maximum resistance of a rheostat is fixed so does its maximum safe current value that can flow through it.Comment'Rheostats' and 'potentiometers' describe applications of variable resistors; they are not alternative words for variable resistors.
Why the armature rheostat of dc is motor kept at maximum resistance position?
It isn't. It is only kept at maximum resistance when the motor is not running. That is done to limit the starting current.
What is the condition for maximum current that can be drawn from a cell?
The maximum current that a cell can deliver flows when the resistance between the terminals of the cell is zero. This situation occurs when the terminals are connected by a conductor with very low resistance, such as a thick wire or a wrench. But not for long.
The Storage battery of a car has an emf of 12 volt if the internal resistance of the battery is 0.4 resistance what is the maximum current that can be drawn from the battery?
You have to imagine the internal resistance as being in parallel with any load you connect. You get the maximum possible current when the load is zero. In this case, just apply Ohm's Law. That is, divide the voltage by the internal resistance.
What happens when dc supply is given to inductor?
The resulting maximum current is limited by the resistance of the inductor. As the current increases from zero to that maximum value, its expanding magnetic field induces a voltage into the inductor which opposes the rise in that current. So, instead of reaching its maximum value instantaneously, it takes some time -determined by the equation:time to maximum current = 5 L / R (seconds)where L = inductance of inductor in henrys, and R = resistance of inductor in ohms.
What is the max power of a 8 inch electric stove heating element?
The maximum power of an 8-inch electric stove heating element typically ranges from 2100 to 2400 watts. This power rating allows the element to heat up quickly and efficiently to cook food evenly. Be sure to consult the manufacturer's guidelines for the specific power rating of your stove's heating element.
Formula used to find the maximum current that can be carried by a resistor if resistance and wattage rating is known?
Manipulate the following equation, to make I the subject: P = I2R, where P = power, I =current, and R = resistance.
How many ohms are in one toaster heating element?
This may vary by make and model of toaster and the intended operating voltage. For a North American toaster designed to operate on a 15 ampere outlet at 120 volts RMS, the hot resistance cannot be any less than 8 ohms. By their nature, heating elements have a lower resistance when cold, so an 8 ohm element needs to be used on a circuit that is protected by a thermal time-delay circuit breaker; an ordinary fuse is likely to burn out during the several seconds it takes for the element to heat up and the current to reach the steady-state "hot" current. Due to the uncertainty of the circuit protection scheme, manufacturers will limit the current, and thus the power level of appliances such as toasters to something less than the maximum theoretical capacity of the circuit. For example, a toaster with an 8 ohm steady state hot resistance will draw 1800 watts. More realistically, the device will be designed to draw 1200 watts, and thus its hot resistance will be 12 ohms.
Batteries have what current?
Battery maximum current is limited by the internal resistance of the battery. As the current is increased towards this maximum, you will notice the output voltage appear to shink towards zero. What this means is the voltage the battery is capable of supplying is being dropped almost completely across the internal resistance, so no real power is available to use.This internal resistance is dependent on the chemical and physical makeup of the battery.
Why use maximum resistance for starting dc shunt motor?
because there is ahigh current flowing through it at the start...
