What is the maximum voltage aluminum foil can conduct?
There is no maximum. Also, foil can conduct an infinite current if it is wide enough.
What is overloading in electric current?
An 'overcurrent' can be an 'overload current' or a 'short-circuit current'. An overload current exists when the load connected to a circuit draws more current than the circuit is designed to carry continuously. A short-circuit current is a high current resulting from a fault between a line conductor and the neutral conductor or earth.
What is The magnitude of an alternation which varies from zero is called its?
I will first answer this from an electrical viewpoint. The maximum positive excursion from zero would be the PEAK, or MAXIMUM portion of the cycle. From a magnetic point, it would be POSITIVE. The negative excursion of the electrical cycle (below zero) would be the MINIMUM. It would be NEGATIVE from a magnetic perspective.
How do you calculate solar cell wattage?
Step 1:Look at the back of the solar panels or consult the manual that came with them. Note the maximum power voltage (Vmp) in volts (V) and the maximum power current (Imp) in amps (A). Multiply the two numbers together to calculate the maximum power of the solar panel in watts (W). For instance, if Vmp is 17.2 V and Imp is 1.17 A, multiply 17.2 by 1.17. The product of these two numbers -- the wattage -- is 20.12 watts (W). The rated power of this particular solar panel would be specified as 20 W.Step 2:Manufacturers measure the maximum power voltage and current at standard conditions of temperature and insolation. The electrical power that a solar panel connected in the home generates will, most of the time, be less than this maximum level. Consult the specification sheet for the solar panels. Look for diagrams called "I-V curves." These diagrams show how the power of a solar panel is lower when there is less sunshine and when the temperature of the cells is above 77 degrees Fahrenheit.Step 3:If your solar panels are producing electricity in the home, you can measure the electrical power directly. Use a digital multimeter to measure the direct-current (DC) voltage produced by the solar panels at the point where they are connected to the charge controller. Write down the voltage measured in volts.Step 4:Measure the DC current in the circuit using the digital multimeter. Follow carefully the instructions in the multimeter manual for this procedure. Write down the current measured in amps. Multiply the voltage by the current to calculate the electrical power in watts.For a global supplier of solar charge from China, see the related link.Power calculationElectrical engineering forum technical and practical tips electrical.10 Amp Solar Charger50% more power.

If you have several panels connected together, you should consult a qualified electrician
What is the terminal potential in the short-circuit?
in the case of short-circuit the current is maximum hence the terminal potential is becomes zero
What is the maximum current ratings for different electrical equipments?
Current depends on the Wattage and the voltage rating of the device.
What is the maximum voltage and current optical fiber can take?
Optical fibers transmit light, not electrical energy.
What do you use fuses in?
Electrical circuits, to limit the maximum current flow. Fuses will "blow", or burn out, and cause an open circuit, to stop the flow of current when it could potentially damage a circuit, system, or device.
Can a electrical motor current be increased?
When the coil is parallel to magnetic field, torque is maximum. When the coil is in vertical position, the torque is minimum. You can't go beyond that.
When is the collector current maximum?
The maximum collector current is normally rated to be the current at which the DC current gain (hFE) falls to 50% of its maximum value. The maximum peak current is Page 2 Operation notes Transistors Rev.A 2/7 rated at a value which ensures reliability within the maximum allowed junction temperature.
What is maximum reverse current?
this is the best current.
What is the maximum current in zinc carbon dry cell?
Maximum Current draw - 20 (milliamperes)
What is formula for calculate maximum current?
volts divided by resistance equals maximum amperage (current)
What is the maximum distance between two electrical manholes?
it is maximum 120 m .
Why is current maximum when short circuited?
when its is short circuited there will not be any drop and hence the current will b maximum when its is short circuited there will not be any drop and hence the current will b maximum
What is meaning oof rated values of current voltage power and torque of an electrical machine?
What it means is that those rated values may not be exceeded, they are the maximum that the machine can take.
What happens to current at resonant frequency?
Current is at maximum
