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 th...
Ohm's law is an important mathematical formula that electricians and physicists use to determine certain measurements in a given circuit. The formula is: V=I×RV=I×R where V is the voltage, measured in volts, I is the amount of current measured in amps or amperage and R is the resistan...
In the unlikely event that you don’t know the wattage of an appliance, but you do know the voltage (almost always 120V) and the resistance (ohms), you won’t be able toconvert watts to amps, but you can calculate the amperage of the device. Ohm’s lawstates: Current (I) = Voltag...

Really, the most useful formulas for vapers, are the three that calculate current (I = V ÷ R) power (P = V x I) and resistance (R = V ÷ I). These will allow you to figure out the current your coil will draw and the wattage that will result. As you increase resistance, curr...
Answer to: According to Ohm's law, how does a) current varies with voltage? b) voltage varies with resistance? c) current varies with resistance?...
Calculate the total resistance of the parallel circuit by using the equation 1/Rtotal = 1/R1 + 1/R2 + 1/R3 + ... + 1/Rn. This equation states that by adding the inverses of all of the individual resistors, you will get the inverse of the total resistance. Pretend that you have ...
Using Ohm's law we can calculate the resistors such that they generate minimum safe resistance together but singly offers an optimal high resistance forcing the current to share the paths equally across all the diodes. Generally a 0.5 ohm resistance will be quite safe for safeguarding the power ...
While there are several methods of measuring current, the most common method is to perform an indirect measurement of the voltage across a precision resistor and using Ohm’s law to measure the current across the resistor. Contents Current Fundamentals How to Make a Current Measurement Recommende...
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. ...
