You can calculate the amount of wire of width W needed to make a coil of radius R and length L by using the formula 2?R x (L/W). This formula is equivalent to the circumference each loop of the wire makes times the number of such loops in the coil. This formula is, however, a...
Write down the information that the problem gives you; in this case, the problem will probably give you the circuit’s power and current. Many physics teachers use problems requiring you to calculate resistance from power and current as a slightly more difficult way to test your knowledge of e...
How to calculate the total length of the wire routed in a layout. It should consider all the metals used for routing and at all levels of hierarchy. [Read in latest Spectrum magazine that the total wire length may reach from 2kms to 10kms for the latest processes and curious to find on...
Calculate the full load current that each wire must carry. If there is only a main circuit breaker, the full load current will be the generator power in watts divided by the voltage. For example, if the generator power is 2400W and it operates at 120V, the full load current is 20A. 2...
Step 1:Identify the Current of the wire, or calculate the Current using Ohm's Law:V=IRwhere I is the Amps in the wire, R is the Resistance of the wire, and V is the Voltage applied to the wire. Step 2:Determine the number of Coulombs of electrons passing through t...
Metal inert gas (MIG) welding machines automatically feed wire through the torch head of the welding gun to the weld site. This wire acts both as the electrode that arcs with the metal being welded to create the weld bead and as filler material to join t
You can calculate the resistance of the wire with the resistance equation. Let's say you have a 120-watt light bulb plugged into a wall socket. The voltage is 120 volts, and a 120-watt bulb has 1 amp flowing through it. You can calculate the resistance of the filament by rearranging ...
where I is the current flowing through the circuit, V is the electric potential difference across the battery, and R is the resistance of the resistor(s) in the circuit. What is Current? Current can seem like a somewhat arbitrary measurement just meant to facilitate a...
How to Calculate the Emitter Current Limiting Resistor in Parallel BJTs It is actually very simple, and could be calculated using Ohm's Law: R = V/I, Where V is the supply voltage used in the circuit, and "I" could be 70% of the transistor's maximum current handling capacity. ...
